No, I don't need the other threads suspended, I just want the current one to not be preempted during particular sections of code. I suppose that I could raise the thread's priority, but that's not terribly well documented and doesn't guarantee that it won't be preempted (I think). What I'm being told by the programmer who's actually using this is: The time-critical stuff only starts when the function returns--it doesn't mean "interrupt everything else and make me high priority", but just "make me high priority and don't let anything interrupt me".
