2703	Here is a matrix of mmap possibilities:
2704	mmap private not fixed
2705	mmap private fixed at somewhere currently unmapped
2706	mmap private fixed at somewhere already mapped
2707	mmap shared not fixed
2708	mmap shared fixed at somewhere currently unmapped
2709	mmap shared fixed at somewhere already mapped
2710	For private mappings, we should verify that changes cannot be read()
2711	back from the file, nor mmap's back from the file at a different
2712	address. (There have been systems where private was not correctly
2713	implemented like the infamous i386 svr4.0, and systems where the
2714	VM page cache was not coherent with the filesystem buffer cache
2715	like early versions of FreeBSD and possibly contemporary NetBSD.)
2716	For shared mappings, we should conversely verify that changes get
2717	propogated back to all the places they're supposed to be.
2718
2719	Grep wants private fixed already mapped.
2720	The main things grep needs to know about mmap are:
2721	* does it exist and is it safe to write into the mmap'd area
2722	* how to use it (BSD variants) */
