For those who may be interested in this (Erann?); Henry Baker has
written a paper on garbage collection called "List Processing in Real
Time on a Serial Computer" which describes a real-time compacting
garbage collector. The article is not new but still worth reading.
Other articles covering the same issues plus a lot of other things
about language implementation, compilation, etc can be found at the
SEL-HPC archive for compilers and interpreters. For those who are
interested in using Lisp in real-time environments, this might be
worth looking into.

Netcom):
