Doc or gen_event:notify/2 Error!

Hello,
   I have found an inconsistency in the docs.

The docs indicate that the return value for gen_event notify is as
follows:

notify(EventMgrRef, Event) -> ok

This makes sense as it is asynchronous. I pass a registered name to a
notify call and if the name is not registered I get an exit(). It is the
same badarg exit that one would expect from

unregistered_name ! message

I think that either the docs should be changed to

notify(EventMgrRef, Event) -> ok | exit() 

or more preferably the notify/2 function should not exit.

Cheers,
Martin
