-+       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()

-+   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 file system buffer cache
-+   like early versions of FreeBSD and possibly contemporary NetBSD.)
-+   For shared mappings, we should conversely verify that changes get
-+   propagated 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:
