4148    Here is a matrix of mmap possibilities:
4149         mmap private not fixed
4150         mmap private fixed at somewhere currently unmapped
4151         mmap private fixed at somewhere already mapped
4152         mmap shared not fixed
4153         mmap shared fixed at somewhere currently unmapped
4154         mmap shared fixed at somewhere already mapped
4155    For private mappings, we should verify that changes cannot be read()
4156    back from the file, nor mmap's back from the file at a different
4157    address.  (There have been systems where private was not correctly
4158    implemented like the infamous i386 svr4.0, and systems where the
4159    VM page cache was not coherent with the file system buffer cache
4160    like early versions of FreeBSD and possibly contemporary NetBSD.)
4161    For shared mappings, we should conversely verify that changes get
4162    propogated back to all the places they're supposed to be.
4163
4164    Grep wants private fixed already mapped.
4165    The main things grep needs to know about mmap are:
4166    * does it exist and is it safe to write into the mmap'd area
4167    * how to use it (BSD variants)  */
