I doubt that our event dispatcher is so bad that libevent would be an order of 
magnitude better.

I'm really interested in numbers here. Someone will have to prototype the 
support and benchmark some real applications and some unreal ones (stress-
test) so we can make a choice.

The most important case for an event dispatcher is actually compatibility with 
other frameworks. Is anyone also pushing Glib to switch to libevent?
