3274 /* Thanks to Mike Haertel and Jim Avera for this test.
3275    Here is a matrix of mmap possibilities:
3276         mmap private not fixed
3277         mmap private fixed at somewhere currently unmapped
3278         mmap private fixed at somewhere already mapped
3279         mmap shared not fixed
3280         mmap shared fixed at somewhere currently unmapped
3281         mmap shared fixed at somewhere already mapped
3282    For private mappings, we should verify that changes cannot be read()
3283    back from the file, nor mmap's back from the file at a different
3284    address.  (There have been systems where private was not correctly
3285    implemented like the infamous i386 svr4.0, and systems where the
3286    VM page cache was not coherent with the filesystem buffer cache
3287    like early versions of FreeBSD and possibly contemporary NetBSD.)
3288    For shared mappings, we should conversely verify that changes get
3289    propogated back to all the places they're supposed to be.
3290
3291    Grep wants private fixed already mapped.
3292    The main things grep needs to know about mmap are:
3293    * does it exist and is it safe to write into the mmap'd area
3294    * how to use it (BSD variants)  */
