2167    Here is a matrix of mmap possibilities:
2168         mmap private not fixed
2169         mmap private fixed at somewhere currently unmapped
2170         mmap private fixed at somewhere already mapped
2171         mmap shared not fixed
2172         mmap shared fixed at somewhere currently unmapped
2173         mmap shared fixed at somewhere already mapped
2174    For private mappings, we should verify that changes cannot be read()
2175    back from the file, nor mmap's back from the file at a different
2176    address.  (There have been systems where private was not correctly
2177    implemented like the infamous i386 svr4.0, and systems where the
2178    VM page cache was not coherent with the filesystem buffer cache
2179    like early versions of FreeBSD and possibly contemporary NetBSD.)
2180    For shared mappings, we should conversely verify that changes get
2181    propogated back to all the places they're supposed to be.
2182
2183    Grep wants private fixed already mapped.
2184    The main things grep needs to know about mmap are:
2185    * does it exist and is it safe to write into the mmap'd area
2186    * how to use it (BSD variants)  */
