3117	Here is a matrix of mmap possibilities:
3118	mmap private not fixed
3119	mmap private fixed at somewhere currently unmapped
3120	mmap private fixed at somewhere already mapped
3121	mmap shared not fixed
3122	mmap shared fixed at somewhere currently unmapped
3123	mmap shared fixed at somewhere already mapped
3124	For private mappings, we should verify that changes cannot be read()
3125	back from the file, nor mmap's back from the file at a different
3126	address. (There have been systems where private was not correctly
3127	implemented like the infamous i386 svr4.0, and systems where the
3128	VM page cache was not coherent with the filesystem buffer cache
3129	like early versions of FreeBSD and possibly contemporary NetBSD.)
3130	For shared mappings, we should conversely verify that changes get
3131	propogated back to all the places they're supposed to be.
3132
3133	Grep wants private fixed already mapped.
3134	The main things grep needs to know about mmap are:
3135	* does it exist and is it safe to write into the mmap'd area
3136	* how to use it (BSD variants) */
