Aside from whether or not I like this API (I have to study it some 
more), here are some comments on the patch:

1. eventhandler_init() is unnecessary.  Statically initialize 
eventhandler_lists and eventhandler_slock instead.

2. What are the interrupt semantics of event handlers?  EHL_LOCK() and 
EHL_UNLOCK() operate as if events can only be issued from a valid 
thread context, never from an interrupt context (otherwise, they would 
need some interrupt projection, as well).
