2203    Here is a matrix of mmap possibilities:
2204         mmap private not fixed
2205         mmap private fixed at somewhere currently unmapped
2206         mmap private fixed at somewhere already mapped
2207         mmap shared not fixed
2208         mmap shared fixed at somewhere currently unmapped
2209         mmap shared fixed at somewhere already mapped
2210    For private mappings, we should verify that changes cannot be read()
2211    back from the file, nor mmap's back from the file at a different
2212    address.  (There have been systems where private was not correctly
2213    implemented like the infamous i386 svr4.0, and systems where the
2214    VM page cache was not coherent with the filesystem buffer cache
2215    like early versions of FreeBSD and possibly contemporary NetBSD.)
2216    For shared mappings, we should conversely verify that changes get
2217    propogated back to all the places they're supposed to be.
2218
2219    Grep wants private fixed already mapped.
