This is an important consideration. If you're relying on a specific
event to finish within a finite amount of time, you're going to have a
race condition where the event could finish later than expected and
you may end up in an invalid state.
Perhaps if you told us what it is you're specif

Hmm... someone correct me if I'm wrong, but I believe the run loop is
re-enterable. So you
There's usleep, but sleeping a thread just for a very small amount of
time in a loop is gonna force a context switch every iteration and
really hurt performance. It might be better to poll or spin.

NSThread has a sleepUntilDate: class method.
In the example below, 0.1 = 1/10th of a second.
