3173	Here is a matrix of mmap possibilities:
3174	mmap private not fixed
3175	mmap private fixed at somewhere currently unmapped
3176	mmap private fixed at somewhere already mapped
3177	mmap shared not fixed
3178	mmap shared fixed at somewhere currently unmapped
3179	mmap shared fixed at somewhere already mapped
3180	For private mappings, we should verify that changes cannot be read()
3181	back from the file, nor mmap's back from the file at a different
3182	address. (There have been systems where private was not correctly
3183	implemented like the infamous i386 svr4.0, and systems where the
3184	VM page cache was not coherent with the filesystem buffer cache
3185	like early versions of FreeBSD and possibly contemporary NetBSD.)
3186	For shared mappings, we should conversely verify that changes get
3187	propogated back to all the places they're supposed to be.
3188
3189	Grep wants private fixed already mapped.
3190	The main things grep needs to know about mmap are:
3191	* does it exist and is it safe to write into the mmap'd area
3192	* how to use it (BSD variants) */
