In a
word, you can't. The fact is the Thread priority constants are implementation dependent, so a priority of 1, 2, and 3 may be identical on Windows and distint on Solaris.
You could try to come up with an algorithm that would have each thread yield and sleep based on your arbitrary numbering but the behavior would not be consistent in all probability. The big problem with threads is you are at the mercy of the OS that creates and schedules the threads.
Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius - and a lot of courage - to move in the opposite direction. - Ernst F. Schumacher
