Thanks. I documented that in Makefile.direct for now, though I haven't
yet checked that in.

> # -DUSE_MMAP use MMAP instead of sbrk to get new memory.
> # Works for Solaris and Irix.
> # -DUSE_MUNMAP causes memory to be returned to the OS under the right
> # circumstances. This currently disables VM-based
> incremental collection.
> # This is currently experimental, and works only under some Unix,
> # Linux and Windows versions.
> This is a little confusing because USE_MUNMAP requires USE_MMAP.
> Under Windows, I can use:
> -DUSE_MMAP -DUSE_MUNMAP
> to make UNMAP work.
