12 | (<unique object reference number> & 3) would work. Give the appearance of
randomness and 1-second resolution, without bogging the CPU by using all the
threads at once. Using appropriate bit shifting and arbitrary fragments of
statistics and whatnot, you can do a really fast calculation that would change
over time and keep things separated a good deal. Sure, you might end up with a
pathological case, but that would be rare and it wouldn't be any worse than
scheduling all the threads at once.

There are, of course, much more efficient methods that could be pulled up by
people who are much more experienced in this sort of programming than I am.
Hell, I'm from a single-process single-task world, and I'm only just getting out
of this crap where all I get to do is run networks... now that I'm back to
writing code again, I should get a good background in this stuff over the next
couple of months.
