3219    Here is a matrix of mmap possibilities:
3220         mmap private not fixed
3221         mmap private fixed at somewhere currently unmapped
3222         mmap private fixed at somewhere already mapped
3223         mmap shared not fixed
3224         mmap shared fixed at somewhere currently unmapped
3225         mmap shared fixed at somewhere already mapped
3226    For private mappings, we should verify that changes cannot be read()
3227    back from the file, nor mmap's back from the file at a different
3228    address.  (There have been systems where private was not correctly
3229    implemented like the infamous i386 svr4.0, and systems where the
3230    VM page cache was not coherent with the filesystem buffer cache
3231    like early versions of FreeBSD and possibly contemporary NetBSD.)
3232    For shared mappings, we should conversely verify that changes get
3233    propogated back to all the places they're supposed to be.
3234
3235    Grep wants private fixed already mapped.
3236    The main things grep needs to know about mmap are:
3237    * does it exist and is it safe to write into the mmap'd area
3238    * how to use it (BSD variants)  */
