2200    Here is a matrix of mmap possibilities:
2201         mmap private not fixed
2202         mmap private fixed at somewhere currently unmapped
2203         mmap private fixed at somewhere already mapped
2204         mmap shared not fixed
2205         mmap shared fixed at somewhere currently unmapped
2206         mmap shared fixed at somewhere already mapped
2207    For private mappings, we should verify that changes cannot be read()
2208    back from the file, nor mmap's back from the file at a different
2209    address.  (There have been systems where private was not correctly
2210    implemented like the infamous i386 svr4.0, and systems where the
2211    VM page cache was not coherent with the filesystem buffer cache
2212    like early versions of FreeBSD and possibly contemporary NetBSD.)
2213    For shared mappings, we should conversely verify that changes get
2214    propogated back to all the places they're supposed to be.
2215
2216    Grep wants private fixed already mapped.
2217    The main things grep needs to know about mmap are:
2218    * does it exist and is it safe to write into the mmap'd area
2219    * how to use it (BSD variants)  */
