2661    Here is a matrix of mmap possibilities:
2662         mmap private not fixed
2663         mmap private fixed at somewhere currently unmapped
2664         mmap private fixed at somewhere already mapped
2665         mmap shared not fixed
2666         mmap shared fixed at somewhere currently unmapped
2667         mmap shared fixed at somewhere already mapped
2668    For private mappings, we should verify that changes cannot be read()
2669    back from the file, nor mmap's back from the file at a different
2670    address.  (There have been systems where private was not correctly
2671    implemented like the infamous i386 svr4.0, and systems where the
2672    VM page cache was not coherent with the filesystem buffer cache
2673    like early versions of FreeBSD and possibly contemporary NetBSD.)
2674    For shared mappings, we should conversely verify that changes get
2675    propogated back to all the places they're supposed to be.
2676
2677    Grep wants private fixed already mapped.
2678    The main things grep needs to know about mmap are:
