I'm signed up to the list again! Thanks to Bill and Marshall for the
friendly nudges.

The MP task implementation is really only interesting for Carbon and
Mac OS 9-only targets; the pthreads implementation is more efficient
and probably safer under Mac OS X/Mach-O.

It was always Bill's thought that the API was portable to cooperative
threads, but I do not believe that this was ever implemented or tested.
Certainly many threaded solutions will not work without preemption,
regardless of the thread library they are built against.
