That works too. I wasn't sure whether or not MAP_SHARED should be
turned on unilaterally (though John correctly states that specifying
neither is an error) so I explictly confined my change to only turning
off MAP_PRIVATE (e.g. you could easily come out of that code with
neither set). I've tested this change and it works just fine. Commit
that baby! :-)
