2735    Here is a matrix of mmap possibilities:
2736         mmap private not fixed
2737         mmap private fixed at somewhere currently unmapped
2738         mmap private fixed at somewhere already mapped
2739         mmap shared not fixed
2740         mmap shared fixed at somewhere currently unmapped
2741         mmap shared fixed at somewhere already mapped
2742    For private mappings, we should verify that changes cannot be read()
2743    back from the file, nor mmap's back from the file at a different
2744    address.  (There have been systems where private was not correctly
2745    implemented like the infamous i386 svr4.0, and systems where the
2746    VM page cache was not coherent with the filesystem buffer cache
2747    like early versions of FreeBSD and possibly contemporary NetBSD.)
2748    For shared mappings, we should conversely verify that changes get
2749    propogated back to all the places they're supposed to be.
2750
2751    Grep wants private fixed already mapped.
2752    The main things grep needs to know about mmap are:
2753    * does it exist and is it safe to write into the mmap'd area
2754    * how to use it (BSD variants)  */
