+	each subscription slot is as an auto-optmizing linked list. Originally it was a uwsgi_dict (now removed from uWSGI) but this
+	would have not be able to support regexp as keys.
+
+	each slot has another circular linked list containing the nodes names
+
+	the structure and system is very similar to uwsgi_dyn_dict already used by the mime type parser
+
+	This system is not mean to run on shared memory. If you have multiple processes for the same app, you have to create
+	a new subscriptions slot list.
+
+	To avoid removal of already using nodes, a reference count system has been implemented
