I've been using MacSimula 4.11 on the Macintosh, and am extremely
impressed with its quality. Every bug I've found has turned out to be
mine, not a compiler problem!

But it has one big deficiency: once my simulation starts running, it keeps
control of the entire machine. No cycles are freed for updating the clock
display, picking up characters from the network, etc. It would be sooo
much nicer if it could run in the background like a normal cooperative
MacCitizen, even though that would of course be much slower, because then
I could use my Mac for some of the other things I need to do, like email.

There is a bunch of Mac interface stuff included, which I have not used so
far because I wanted to keep my simulation portable, but I wonder if that
could be used to add background capability. Has anyone had experience with
the Mac version, to advise me if this direction is worth pursuing? Or is
there an undocumented switch for the compiler that makes it generate more
Mac-friendly code?
