3172	Here is a matrix of mmap possibilities:
3173	mmap private not fixed
3174	mmap private fixed at somewhere currently unmapped
3175	mmap private fixed at somewhere already mapped
3176	mmap shared not fixed
3177	mmap shared fixed at somewhere currently unmapped
3178	mmap shared fixed at somewhere already mapped
3179	For private mappings, we should verify that changes cannot be read()
3180	back from the file, nor mmap's back from the file at a different
3181	address. (There have been systems where private was not correctly
3182	implemented like the infamous i386 svr4.0, and systems where the
3183	VM page cache was not coherent with the filesystem buffer cache
3184	like early versions of FreeBSD and possibly contemporary NetBSD.)
3185	For shared mappings, we should conversely verify that changes get
3186	propogated back to all the places they're supposed to be.
3187
3188	Grep wants private fixed already mapped.
3189	The main things grep needs to know about mmap are:
3190	* does it exist and is it safe to write into the mmap'd area
3191	* how to use it (BSD variants) */
