2857/* Thanks to Mike Haertel and Jim Avera for this test.
2858 Here is a matrix of mmap possibilities:
2859 mmap private not fixed
2860 mmap private fixed at somewhere currently unmapped
2861 mmap private fixed at somewhere already mapped
2862 mmap shared not fixed
2863 mmap shared fixed at somewhere currently unmapped
2864 mmap shared fixed at somewhere already mapped
2865 For private mappings, we should verify that changes cannot be read()
2866 back from the file, nor mmap's back from the file at a different
2867 address. (There have been systems where private was not correctly
2868 implemented like the infamous i386 svr4.0, and systems where the
2869 VM page cache was not coherent with the filesystem buffer cache
2870 like early versions of FreeBSD and possibly contemporary NetBSD.)
2871 For shared mappings, we should conversely verify that changes get
2872 propogated back to all the places they're supposed to be.
2873
2874 Grep wants private fixed already mapped.
2875 The main things grep needs to know about mmap are:
2876 * does it exist and is it safe to write into the mmap'd area
2877 * how to use it (BSD variants) */
