2088    Here is a matrix of mmap possibilities:
2089         mmap private not fixed
2090         mmap private fixed at somewhere currently unmapped
2091         mmap private fixed at somewhere already mapped
2092         mmap shared not fixed
2093         mmap shared fixed at somewhere currently unmapped
2094         mmap shared fixed at somewhere already mapped
2095    For private mappings, we should verify that changes cannot be read()
2096    back from the file, nor mmap's back from the file at a different
2097    address.  (There have been systems where private was not correctly
2098    implemented like the infamous i386 svr4.0, and systems where the
2099    VM page cache was not coherent with the filesystem buffer cache
2100    like early versions of FreeBSD and possibly contemporary NetBSD.)
2101    For shared mappings, we should conversely verify that changes get
2102    propogated back to all the places they're supposed to be.
2103
2104    Grep wants private fixed already mapped.
2105    The main things grep needs to know about mmap are:
2106    * does it exist and is it safe to write into the mmap'd area
2107    * how to use it (BSD variants)  */
