2719    Here is a matrix of mmap possibilities:
2720         mmap private not fixed
2721         mmap private fixed at somewhere currently unmapped
2722         mmap private fixed at somewhere already mapped
2723         mmap shared not fixed
2724         mmap shared fixed at somewhere currently unmapped
2725         mmap shared fixed at somewhere already mapped
2726    For private mappings, we should verify that changes cannot be read()
2727    back from the file, nor mmap's back from the file at a different
2728    address.  (There have been systems where private was not correctly
2729    implemented like the infamous i386 svr4.0, and systems where the
2730    VM page cache was not coherent with the filesystem buffer cache
2731    like early versions of FreeBSD and possibly contemporary NetBSD.)
2732    For shared mappings, we should conversely verify that changes get
2733    propogated back to all the places they're supposed to be.
2734
2735    Grep wants private fixed already mapped.
2736    The main things grep needs to know about mmap are:
2737    * does it exist and is it safe to write into the mmap'd area
2738    * how to use it (BSD variants)  */
