2851    Here is a matrix of mmap possibilities:
2852         mmap private not fixed
2853         mmap private fixed at somewhere currently unmapped
2854         mmap private fixed at somewhere already mapped
2855         mmap shared not fixed
2856         mmap shared fixed at somewhere currently unmapped
2857         mmap shared fixed at somewhere already mapped
2858    For private mappings, we should verify that changes cannot be read()
2859    back from the file, nor mmap's back from the file at a different
2860    address.  (There have been systems where private was not correctly
2861    implemented like the infamous i386 svr4.0, and systems where the
2862    VM page cache was not coherent with the filesystem buffer cache
2863    like early versions of FreeBSD and possibly contemporary NetBSD.)
2864    For shared mappings, we should conversely verify that changes get
2865    propogated back to all the places they're supposed to be.
2866
2867    Grep wants private fixed already mapped.
2868    The main things grep needs to know about mmap are:
2869    * does it exist and is it safe to write into the mmap'd area
2870    * how to use it (BSD variants)  */
