The problem with this is that one often creates a thread so
that it can do some possibly blocking operation without
stopping the rest of the program.  If the thread is blocked, it
can't check the event.  If the thread isn't going to block,
then why create a thread?  [Yes, there are other reasons for
splitting something into a thread, but in many cases I create a
thread specifically because it's goign to block.]
