+ mmap private fixed at somewhere currently unmapped

+ 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()

+ 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:
+ * does it exist and is it safe to write into the mmap'd area
+ * how to use it (BSD variants) */
