Hans Boehm's GC is actually really, really good. Before you embark on a massive engineering effort that will likely lead to little gain and a lot of pain, I would measure the overheads very carefully.

(I can't recall for sure but I believe I had this conversation with Martin in a taxi ride not too long ago :)
