The code that implements pass in ceval.c could easily be modified to
periodically call whatever Mac toolbox function is used to release the
processor. Unfortunately, the Mac-specific source code seems not to be
under CVS control, so while I can see some tantalizing hints of what needs
doing in the source on my Linux machine, I can't suggest anything specific.
I'm sure Jack or someone else will know precisely what needs doing.
