2830	Here is a matrix of mmap possibilities:

2834	mmap shared not fixed
2835	mmap shared fixed at somewhere currently unmapped
2836	mmap shared fixed at somewhere already mapped
2837	For private mappings, we should verify that changes cannot be read()
2838	back from the file, nor mmap's back from the file at a different
2839	address. (There have been systems where private was not correctly
2840	implemented like the infamous i386 svr4.0, and systems where the
2841	VM page cache was not coherent with the filesystem buffer cache
2842	like early versions of FreeBSD and possibly contemporary NetBSD.)
2843	For shared mappings, we should conversely verify that changes get
2844	propogated back to all the places they're supposed to be.
2845
2846	Grep wants private fixed already mapped.
2847	The main things grep needs to know about mmap are:

2849	* how to use it (BSD variants) */
