Cool!

I think too many extension modules will crash with pymalloc due to
PyObject_Del/PyMem_Del confusion (e.g. zodb, which scared the crap out
of me last week when I thought it was something I'd done on the
release22-maint branch).

OTOH, they probably won't get fixed until people start using pymalloc
all the time...

Cheers,
