On further discussion off-list, a suggestion was made to use
OTEnterNotifer and OTLeaveNotifier. This is a correct solution only
if the following is true:
If a thread calls OTEnterNotifier for an endpoint, and the notifier
for that endpoint is currently executing in a secondary thread,
OTEnterNotifier will not return before the notifier returns.
(In other words, I need to know not only that a notifier will not
fire while I am inside the Enter/Leave block, but that the
Enter/Leave block will not preempt a notifier that fired before the
Enter/Leave block.)
Is this true?
