2730    Here is a matrix of mmap possibilities:
2731         mmap private not fixed
2732         mmap private fixed at somewhere currently unmapped
2733         mmap private fixed at somewhere already mapped
2734         mmap shared not fixed
2735         mmap shared fixed at somewhere currently unmapped
2736         mmap shared fixed at somewhere already mapped
2737    For private mappings, we should verify that changes cannot be read()
2738    back from the file, nor mmap's back from the file at a different
2739    address.  (There have been systems where private was not correctly
2740    implemented like the infamous i386 svr4.0, and systems where the
2741    VM page cache was not coherent with the filesystem buffer cache
2742    like early versions of FreeBSD and possibly contemporary NetBSD.)
2743    For shared mappings, we should conversely verify that changes get
2744    propogated back to all the places they're supposed to be.
2745
2746    Grep wants private fixed already mapped.
2747    The main things grep needs to know about mmap are:
2748    * does it exist and is it safe to write into the mmap'd area
2749    * how to use it (BSD variants)  */
