Events are self-contained synchronization objects that are not explicitly
associated with external "locks". When you wait on a manual reset event you
will wait until the event becomes signalled, while you were waiting (well
that's the basic action of wait for all events - manual reset or
auto-reset). If you think of events as if they were condition variables then
they seems "broken" because you get "lost wakeups" etc - but they are not
CV's and you use them differently. You combine Events with "locks" using
methods like "signalObjectAndWait" that allows you to atomically "release" a
lock object and wait on the event object.

This is the win32 synchronization model - I don't know if they have changed
it for C# but I'm assuming they just provide wrapper objects.
