Well, there were bugs in it until recently. As in, a commit between  
2.0.9 and 2.0.10 that would prevent this from working as designed:

http://levent.git.sourceforge.net/git/gitweb.cgi?p=levent/levent;a=commit;h=5beeec9d43cbf7de700a9a0fd7d144a341e102c2

event_active takes a struct event*, so it does tell the thread what to  
do: it triggers a specific callback in an event_loop, which can be  
across threads. I use this in one program to implement a thread pool:  
I have a "main" event_loop which does most network I/O processing,  
then I use event_active to pass some specific tasks to other t threads.
