[Ace-users] [ace-users] thread priority

In the case of three threads on a dual-core machine the two highest
priority threads should run and the lowest priority thread should run
when the other threads are done.  Naturally, this analysis assumes
your OS honors thread priorities, which may or may not be the case
depending on OS-level factors outside the control of ACE.

Thanks,
