-	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 *);
