malloc() and free(). See _PyObject_ArenaMalloc (etc) in

Oh, sorry, I forgot how to read. If ARENAS_USE_MMAP is on it uses
mmap(). I can't figure out when or how MAP_ANONYMOUS gets set, but
if I step into the _PyObject_Arena.alloc() it indeed calls
_PyObject_ArenaMmap() which uses mmap(). So, huzzah!, we use mmap()
to allocate our enormous 256kb arenas.<br>
