From the pod:
hits=>$int
A watcher increments 'hits' every time it registers an event.
Signals in
quick succession can be clumped into a single event.
What happens if two sigs come in at the same time? Will all signals
be
handled by the cb accordingly?
Also, does signal handling using Event.pm suffer from the same
problems
in perl where a signal handler that does something that malloc()'s?
ie print().

I dunno .. sounded good ? :)

Ok. I have a better understanding now. loop until unloop() (which
needs to be
in a cb) So I can create many event watchers, and once I loop(),
they all kick off.

Cool. :)
