Re: The taming of the before-gc-hook (was Re: Upcoming 1.3.2 release)
I don't think Guile should include any Scheme-level GC hooks. That's
a meta-level crossing that I think is particularly nasty.
We should certainly provide both before- and after-gc hooks at the C
level. These can be used safely and productively (as in SCWM's case),
and they give foolish users the opportunity to hang themselves
however they please.
