-
-	1) the runqueue, cores ready to be run are appended in this list
-
-	2) the fd list, this is a list of monitored file descriptors, a core can wait for all the file descriptors it needs
-
-	3) the timeout value, if set the current core will timeout aftert he specified number of seconds (unless an event cancel it)

-	Exceptions management
-
-	generally exceptions are printed in the logs, but if you enable
-	an exception manager they will be stored in a (relatively big) uwsgi packet
-	with the following structure.
-
-	"vars" -> keyval of request vars
-	"backtrace" -> list of backtrace lines. Each line is a list of 5 elements filename,line,function,text,custom
-	"unix" -> seconds since the epoch
-	"class" -> the exception class
-	"msg" -> a text message mapped to the extension
-	"repr" -> a text message mapped to the extension in language-specific gergo
-	"wid" -> worker id
-	"core" -> the core generating the exception
-	"pid" -> pid of the worker
-	"node" -> hostname
-
-	Other vars can be added, but you cannot be sure they will be used by exceptions handler.
-
-	The exception-uwsgi packet is passed "as is" to the exception handler
-
-	Exceptions hooks:
-	
-		a request plugin can export that hooks:
-	
-		struct uwsgi_buffer *backtrace(struct wsgi_request *);
-		struct uwsgi_buffer *exception_class(struct wsgi_request *);
-		struct uwsgi_buffer *exception_msg(struct wsgi_request *);
-		struct uwsgi_buffer *exception_repr(struct wsgi_request *);
-		void exception_log(struct wsgi_request *);
-
-		Remember to reset the exception status (if possibile) after each call
-
-	Exceptions catcher:
-
-		This is a special development-mode in which exceptions are printed
-		to the HTTP client.

-/*
-
-	uWSGI metrics subsystem
-
-	a metric is a node in a tree reachable via a numeric id (OID, in SNMP way) or a simple string:
-
-	uwsgi.worker.1.requests
-	uwsgi.custom.foo.bar
-
-	the oid representation:
-
-		1.3.6.1.4.1.35156.17 = iso.org.dod.internet.private.enterprise.unbit.uwsgi
-		1.3.6.1.4.1.35156.17.3.1.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.worker.1.requests
-		1.3.6.1.4.1.35156.17.3.1.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.worker.1.requests
-		1.3.6.1.4.1.35156.17.3.1.2.1.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.worker.1.core.1.requests
-		1.3.6.1.4.1.35156.17.4.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.system.load_avg
-		...
-
-	each metric is a collected value with a specific frequency (a frequency of zero means the value is re-computed every time)
-	metrics are meant for numeric values signed 64 bit, but they can be exposed as:
-
-	gauge
-	counter
-	absolute
-
-	both 32 and 64bit, both signed and unsigned
-
-	metrics are managed by a dedicated thread (in the master) holding a linked list of all the items. For few metrics it is a good (read: simple) approach,
-	but you can cache lookups in a uWSGI cache for really big list.
-
-	struct uwsgi_metric *um = uwsgi_register_metric("worker.1.requests", "3.1.1", UWSGI_METRIC_COUNTER, UWSGI_METRIC_PTR, &uwsgi.workers[1].requests, 0, NULL);
-	prototype: struct uwsgi_metric *uwsgi_register_metric(char *name, char *oid, uint8_t value_type, uint8_t collect_way, void *ptr, uint32_t freq, void *custom);
-
-	value_type = UWSGI_METRIC_COUNTER/UWSGI_METRIC_GAUGE/UWSGI_METRIC_ABSOLUTE
-	collect_way = UWSGI_METRIC_PTR -> get from a pointer / UWSGI_METRIC_FUNC -> get from a func with the prototype int64_t func(struct uwsgi_metric *); / UWSGI_METRIC_FILE -> get the value from a file, ptr is the filename
-
-	when freq is zero the value is recomputed whenever requested, otherwise the metrics thread compute it every time the frequency is elapsed and caches it
-
-	For some metric (or all ?) you may want to hold a value even after a server reload. For such a reason you can specify a directory on wich the server (on startup/restart) will look for
-	a file named like the metric and will read the initial value from it. It may look an old-fashioned and quite inefficient way, but it is the most versatile for a sysadmin (allowing him/her
-	to even modify the values manually)
-
-	When registering a metric with the same name of an already registered one, the new one will overwrite the previous one. This allows plugins writer to override default behaviours
-
-	Applications are allowed to update metrics (but they cannot register new ones), with simple api funcs:
-
-	uwsgi.metric_set("worker.1.requests", N)
-	uwsgi.metric_inc("worker.1.requests", N=1)
-	uwsgi.metric_dec("worker.1.requests", N=1)
-	uwsgi.metric_mul("worker.1.requests", N=1)
-	uwsgi.metric_div("worker.1.requests", N=1)
-
-	and obviously they can get values:
-
-	uwsgi.metric_get("worker.1.requests", no_cache|force=False)
-	if the second parameter is True, the value is recomputed (but if it is a metric with a cache, the cache value will not be updated accordingly, this is the job of the metric thread)
-
-	Updating metrics from your app MUST BE ATOMIC, for such a reason a uWSGI rwlock is initialized on startup and used for each operation (simple reading from a metric does not require locking)
-
-	Metrics can be updated from the internal routing subsystem too:
-
-		route-if = equal:${REQUEST_URI};/foobar metricinc:foobar.test 2
-
-	and can be accessed as ${metric[foobar.test]}
-
-	The stats server exports the metrics list in the "metrics" attribute (obviously some info could be redundant)
