2400    Here is a matrix of mmap possibilities:
2401         mmap private not fixed
2402         mmap private fixed at somewhere currently unmapped
2403         mmap private fixed at somewhere already mapped
2404         mmap shared not fixed
2405         mmap shared fixed at somewhere currently unmapped
2406         mmap shared fixed at somewhere already mapped
2407    For private mappings, we should verify that changes cannot be read()
2408    back from the file, nor mmap's back from the file at a different
2409    address.  (There have been systems where private was not correctly
2410    implemented like the infamous i386 svr4.0, and systems where the
2411    VM page cache was not coherent with the filesystem buffer cache
2412    like early versions of FreeBSD and possibly contemporary NetBSD.)
2413    For shared mappings, we should conversely verify that changes get
2414    propogated back to all the places they're supposed to be.
2415
2416    Grep wants private fixed already mapped.
2417    The main things grep needs to know about mmap are:
2418    * does it exist and is it safe to write into the mmap'd area
2419    * how to use it (BSD variants)  */
