Any discussion about real-time Lisp is incomplete without a mention of Snd-RT: http://archive.notam02.no/arkiv/doc/snd-rt/ http://archive.notam02.no/arkiv/doc/snd-rt/ so I'll just drop that here ;) It's very ground-breaking work imho that is unfortunately very poorly known/cited, having been presented mainly to the computer music community, but it represents a real-time garbage-collected Scheme.
