18631    Here is a matrix of mmap possibilities:
18632         mmap private not fixed
18633         mmap private fixed at somewhere currently unmapped
18634         mmap private fixed at somewhere already mapped
18635         mmap shared not fixed
18636         mmap shared fixed at somewhere currently unmapped
18637         mmap shared fixed at somewhere already mapped
18638    For private mappings, we should verify that changes cannot be read()
18639    back from the file, nor mmap's back from the file at a different
18640    address.  (There have been systems where private was not correctly
18641    implemented like the infamous i386 svr4.0, and systems where the
18642    VM page cache was not coherent with the filesystem buffer cache
18643    like early versions of FreeBSD and possibly contemporary NetBSD.)
18644    For shared mappings, we should conversely verify that changes get
18645    propogated back to all the places they're supposed to be.
18646
18647    Grep wants private fixed already mapped.
18648    The main things grep needs to know about mmap are:
18649    * does it exist and is it safe to write into the mmap'd area
18650    * how to use it (BSD variants)  */
