The challenge there is coming up with a good name for PYALLOC_PYMEM.

I think Victor's names for the domains work well:
- "PYALLOC_" prefix to say "this is an allocation domain"
- "PYMEM_RAW" suffix for PyMem_RawMalloc/Realloc/Free
- "PYMEM" suffix for PyMem_Malloc/Realloc/Free
- "PYOBJECT" suffix for PyObject_Malloc/Realloc/Free

Although, there's a copy-and-paste error in the domain definitions (2
*Reallocs in each entry and no *Frees).

If Guido doesn't want to do it, I'm happy to. Antoine would be a good
choice too, since he's the one who suggested taking the time to thrash
out the API details in a PEP (which I agree has substantially improved
the end result).
