Nice garbage collector for C extensions!

[Dominic]

I think it had been done in the
1.5 or 1.4 days....
I therefore assume it did not
work quite as advertised.
Probably memory consumption is
much higher and less deterministic
than with reference counting.
PLT scheme seems to use this
garbage collector and it
consumes 40-50 MB, but including
GUI with editing and interactive
shell.

Maybe someone else who knows more
about this topic can comment or
give reference

ciao,
