Can you give examples of how it's not reliable? I'm currently using it in one of my projects, so if it has problems, I need to know about them.
On the main topic: I think that a good tracing garbage collector would probably be a good idea. I've been having a real headache binding python to my C library via ctypes, and a large part of that problem is that I've got two different garbage collectors (python and bdwgc). I think I've got it worked out at this point, but it would have been convenient to get memory allocated from python's garbage collected heap on the C-side. Lot fewer headaches.
Thanks,
