I've actually been working on a patch recently that does this, and will 
probably be RFC'ing it here soon. It overrides the mmap/munmap calls and 
redirects them to use the process heap when possible. You have to be careful, 
though, because 'mmap' uses off_t. On 32-bit systems this is by default a 32-
bit type, but with _FILE_OFFSET_BITS=64, off_t becomes a 64-bit type and mmap 
is redirected to mmap64.
