You could do this yourself, I think, by:

1) create your own backing file of the appropriate size
2) mmap it into your address space
3) tell your own malloc() routine that that's where it should
   get memory from.

Any problems with that? (besides not being the system standard,
and the reduction of swapping efficiency caused by going through
the file system).
