Last time I did some GC benchmarks (unrelated to Python), Boehm GC
came up surprisingly fast. I suppose it's faster than malloc +
reference counting (not sure how much amortizing malloc calls helps).

I don't like the idea of a conservative GC at all in general, but
Boehm GC seems to have very good quality, and it's easy to use from
the point of view of a C API.
