Just to repeat myself: there were false alarms before. The interleaving
you describe could equally well happen if a new signal is sent just
after the old code executes WaitForSingleObjectEx and sees that a
previous signal is waiting for it. Both old and new signals can be
cleared by the recipient before the second signal sender gets as far as
setting the event.
