3058 mmap shared not fixed
3059 mmap shared fixed at somewhere currently unmapped
3060 mmap shared fixed at somewhere already mapped
3061 For private mappings, we should verify that changes cannot be read()
3062 back from the file, nor mmap's back from the file at a different
3063 address. (There have been systems where private was not correctly
3064 implemented like the infamous i386 svr4.0, and systems where the
3065 VM page cache was not coherent with the filesystem buffer cache
3066 like early versions of FreeBSD and possibly contemporary NetBSD.)
3067 For shared mappings, we should conversely verify that changes get
3068 propogated back to all the places they're supposed to be.
3069
3070 Grep wants private fixed already mapped.
3071 The main things grep needs to know about mmap are:
3072 * does it exist and is it safe to write into the mmap'd area
3073 * how to use it (BSD variants) */
