2706    Here is a matrix of mmap possibilities:
2707         mmap private not fixed
2708         mmap private fixed at somewhere currently unmapped
2709         mmap private fixed at somewhere already mapped
2710         mmap shared not fixed
2711         mmap shared fixed at somewhere currently unmapped
2712         mmap shared fixed at somewhere already mapped
2713    For private mappings, we should verify that changes cannot be read()
2714    back from the file, nor mmap's back from the file at a different
2715    address.  (There have been systems where private was not correctly
2716    implemented like the infamous i386 svr4.0, and systems where the
2717    VM page cache was not coherent with the filesystem buffer cache
2718    like early versions of FreeBSD and possibly contemporary NetBSD.)
2719    For shared mappings, we should conversely verify that changes get
2720    propogated back to all the places they're supposed to be.
2721
2722    Grep wants private fixed already mapped.
2723    The main things grep needs to know about mmap are:
2724    * does it exist and is it safe to write into the mmap'd area
2725    * how to use it (BSD variants)  */
