Great.

I think the best we can do is keep the thing in a separate branch. It's already too late to have, say, a configure-time option to choose GCs (because I did not plan to do this when I started). It would have been quite hard anyway since the current GC code is quite entangled with the rest of Guile in some places. Does that seem like a reasonable plan? Thanks, Ludo'.
