Sandboxed Python: memory limits?

You can adjust the implementations of PyMem_Malloc and PyObject_Malloc.
This would catch many allocations, but not all of them. If you adjust
PyMem_MALLOC instead of PyMem_Malloc, you catch even more allocations -
but extensions modules which directly call malloc() still would bypass
this accounting.
