-/* Thanks to Mike Haertel and Jim Avera for this test.
-   Here is a matrix of mmap possibilities:
-	mmap private not fixed
-	mmap private fixed at somewhere currently unmapped
-	mmap private fixed at somewhere already mapped
-	mmap shared not fixed
-	mmap shared fixed at somewhere currently unmapped
-	mmap shared fixed at somewhere already mapped
-   For private mappings, we should verify that changes cannot be read()
-   back from the file, nor mmap's back from the file at a different
-   address.  (There have been systems where private was not correctly
-   implemented like the infamous i386 svr4.0, and systems where the
-   VM page cache was not coherent with the filesystem buffer cache
-   like early versions of FreeBSD and possibly contemporary NetBSD.)
-   For shared mappings, we should conversely verify that changes get
-   propogated back to all the places they're supposed to be.
-
-   Grep wants private fixed already mapped.
-   The main things grep needs to know about mmap are:
-   * does it exist and is it safe to write into the mmap'd area
-   * how to use it (BSD variants)  */
