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.

This is hard to google for because they are such common words:
how do I delay, wait, pause for a tenth of a second?
I don't want to use NSTimer because I just want to resume where I
left off. I don't want to be in a tight loop because I need the
system to finish something. I just want to pause execution for a
short time. I think there was a wait() in OS9. I found a wait() in
wait.h but it wants an int * and made me nervous.
Specifically, when I send a fetch message to an NSArrayController,
it sometimes takes a fraction of a second for its selection to
become valid. Currently I fire an NSTimer to call a 'part 2' method
to finish what I am doing (scrolling the selection into view), but
it lacks niceness.
