I think there's a way to enable heavier malloc debugging than the
normal --with-pydebug. You'll have to enable it manually by editing
Python.h I believe. Though it may already be on if you define
Py_DEBUG. (Is WITH_PYMALLOC always on?) Ther may also be a libmalloc
that enables heavier debugging; the malloc man page would have info.
