/* 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) */
