AnyOf releases its references to other events once it has fired, so the 
problem is that the various nested AnyOf's with events that don't fire, are 
not getting garbage collected.

It seems the natural fix for this would be to make AnyOf automatically 
"flatten" any nested AnyOf's into itself, so that there is never such a 
thing as a nested AnyOf.  I'll try to implement this along with the other 
changes I've mentioned for events.  (i.e., retaining socket and signal 
events whenever they callbacks active, rather than using weak references
