I've not really looked into tuning the GC. It isn't a bad idea, but back
when I considered doing so, I (correctly) decided that darcs' memory
behavior would change fast enough that tuning the GC wouldn't be
worthwhile. In fact, the hideous_malloc_hack (which is available as a
configure option) dates from that time, and I keep thinking I should remove
I guess darcs is stabilizing enough, and we've now got enough developers,
so that it may be worthwhile for someone to figure out how to improve
interactions with the GC. I'm not sure, but I myself find the subject of
tuning the GC a bit frightening.

The contents of ForeignPtrs--which are the large objects in darcs--are
never copied, since the GC doesn't manage their contents.
