Are you sure it plays nice with the standard memory allocation functions
(malloc/free)? That is unlikely due to use of a GC. The doc I wrote shows
what you have to do to get CPython to play nice.
Additionally I need pypy's behaviour to be deterministic. I was getting
different behaviour from just running a test versus running under gdb with a
breakpoint in one of my C functions and just hitting continue once it hit!
The most promising thing looked to me to be the refcounting GC but that
doesn't compile - the error message implied it had something to do with not
supporting weakrefs.
