Comment(by dimpase):
Replying to [comment:27 was]:
> From my memory of libGAP the GC and the large integer arithmetic are
totally orthogonal/irrelevant. I think working on libGAP whenever
somebody has the interest (!) is a good idea, since it really will be a
major, major plus for Sage when it starts working.
I'll try to get access to GAP 4.5 for Sage as soon as possible.
As I understood from GAP people, their current GC is a major headache
making it hard to write a "usual" library interface,
which might be much nicer to have...
AFAIK, Bohm's GC is more manageable in this respect.
Well, perhaps indeed the changes in 4.5 aren't that big to warrant putting
this on old.
