3126	Here is a matrix of mmap possibilities:
3127	mmap private not fixed
3128	mmap private fixed at somewhere currently unmapped
3129	mmap private fixed at somewhere already mapped
3130	mmap shared not fixed
3131	mmap shared fixed at somewhere currently unmapped
3132	mmap shared fixed at somewhere already mapped
3133	For private mappings, we should verify that changes cannot be read()
3134	back from the file, nor mmap's back from the file at a different
3135	address. (There have been systems where private was not correctly
3136	implemented like the infamous i386 svr4.0, and systems where the
3137	VM page cache was not coherent with the filesystem buffer cache
3138	like early versions of FreeBSD and possibly contemporary NetBSD.)
3139	For shared mappings, we should conversely verify that changes get
3140	propogated back to all the places they're supposed to be.
3141
3142	Grep wants private fixed already mapped.
3143	The main things grep needs to know about mmap are:
3144	* does it exist and is it safe to write into the mmap'd area
3145	* how to use it (BSD variants) */
