I would like to point out here that, contrary to popular believe, 
the pre-X Mac OS *does* support preemptive threads.  Boost Threads 
runs preemptively on Mac OS 8.6 and 9.x (the "Classic" Mac OS), and 
Mac OS X 10.1.x.  The implementation uses MP Tasks, which have been 
around in one form or another for over 5 years.  Currently, the 
only available build is for Carbon, but a non-Carbon version would 
only require one class to be replaced, should there be demand for 
such a thing.
