3011    Here is a matrix of mmap possibilities:
3012         mmap private not fixed
3013         mmap private fixed at somewhere currently unmapped
3014         mmap private fixed at somewhere already mapped
3015         mmap shared not fixed
3016         mmap shared fixed at somewhere currently unmapped
3017         mmap shared fixed at somewhere already mapped
3018    For private mappings, we should verify that changes cannot be read()
3019    back from the file, nor mmap's back from the file at a different
3020    address.  (There have been systems where private was not correctly
3021    implemented like the infamous i386 svr4.0, and systems where the
3022    VM page cache was not coherent with the filesystem buffer cache
3023    like early versions of FreeBSD and possibly contemporary NetBSD.)
3024    For shared mappings, we should conversely verify that changes get
3025    propogated back to all the places they're supposed to be.
3026
3027    Grep wants private fixed already mapped.
3028    The main things grep needs to know about mmap are:
3029    * does it exist and is it safe to write into the mmap'd area
3030    * how to use it (BSD variants)  */
