I am using xlisp 2.0 on a macintosh and have been thinking of writing
a MIDI program using it.  It would need to be pseudo-realtime, with
the actual I/O running off interrupts, and communicating to the Xlisp
program via circular queues.  

Question: does anybody have a good idea of what the maximum time required
by a garbage collection is?  I can bound the workspace size, <1M (how
much mem my mac has).  I would like to see how big I'd need to make my queues
to avoid losing data during a GC.

Any information would be helpful.  I may summarize if anough people are
crazy enough to do realtime work in lisp.

Thanks in advance,
