2705    Here is a matrix of mmap possibilities:
2706         mmap private not fixed
2707         mmap private fixed at somewhere currently unmapped
2708         mmap private fixed at somewhere already mapped
2709         mmap shared not fixed
2710         mmap shared fixed at somewhere currently unmapped
2711         mmap shared fixed at somewhere already mapped
2712    For private mappings, we should verify that changes cannot be read()
2713    back from the file, nor mmap's back from the file at a different
2714    address.  (There have been systems where private was not correctly
2715    implemented like the infamous i386 svr4.0, and systems where the
2716    VM page cache was not coherent with the filesystem buffer cache
2717    like early versions of FreeBSD and possibly contemporary NetBSD.)
2718    For shared mappings, we should conversely verify that changes get
2719    propogated back to all the places they're supposed to be.
2720
2721    Grep wants private fixed already mapped.
2722    The main things grep needs to know about mmap are:
2723    * does it exist and is it safe to write into the mmap'd area
2724    * how to use it (BSD variants)  */
