Re: gc notes available

I'm concerned first with reducing the overall cost of GC, and second
with providing acceptable interactive behavior.

I have read that most incremental collectors limit the absolute pause
length, but consume more time overall than non-incremental collectors.
I don't want to come out of this with Guile spending *more* time in
the collector than it does now.  I'm not interested enough in games
and animations to make that trade.

If someone gives us an incremental collector that's *more*
efficient, I'm certainly not going to complain.
