Yes. See attached patch pymalloc_frag.diff
It's the first time I'm playing with autotools, so please review this part really carefully ;-)

Yes. But since it probably only affects glibc/eglibc malloc versions, I guess that target implementations are likely to provide mallopt(M_MMAP_THRESHOLD).
Also, performing an anonymous mappings varies even among Unices (the mmapmodule code is scary). I'm not talking about Windows, which I don't know at all.
