Why do you prefer mmap to posix_memalign? I'm almost done with the implementation you suggested (I'm testing the MMAP version now, then I'll go through with various combinations of HAVE_MMAP, HAVE_MAP_ANONYMOUS, and HAVE_POSIX_MEMALIGN, but it strikes me that my bookkeeping for mmap could slow things down if many blocks were allocated (I'm storing the ptr->size map in a simple linked list, but even something more efficient would eventually slow).
