Help with understanding cues/syncs

Given the above, it should be possible to see that sleep 0 is essentially a null operation with respect to the thread’s notion of time - as it adds 0 to it. It also may cause the thread to actually POSIX sleep if it’s too far ahead of itself (this is just to ensure that the actual temporal execution of the threads is within some acceptable bounds).

I hope that this helps.

I does help, I think. The trouble with prior knowlege is that it often brings expectations and assumptions rather than useful understanding. I think I just need to forget a few more things and learn to think more in the way that you were when setting all this up
