2332    Here is a matrix of mmap possibilities:
2333         mmap private not fixed
2334         mmap private fixed at somewhere currently unmapped
2335         mmap private fixed at somewhere already mapped
2336         mmap shared not fixed
2337         mmap shared fixed at somewhere currently unmapped
2338         mmap shared fixed at somewhere already mapped
2339    For private mappings, we should verify that changes cannot be read()
2340    back from the file, nor mmap's back from the file at a different
2341    address.  (There have been systems where private was not correctly
2342    implemented like the infamous i386 svr4.0, and systems where the
2343    VM page cache was not coherent with the filesystem buffer cache
2344    like early versions of FreeBSD and possibly contemporary NetBSD.)
2345    For shared mappings, we should conversely verify that changes get
2346    propogated back to all the places they're supposed to be.
2347
2348    Grep wants private fixed already mapped.
2349    The main things grep needs to know about mmap are:
2350    * does it exist and is it safe to write into the mmap'd area
2351    * how to use it (BSD variants)  */
