   No...but there are systems (like BSDI) where mmap is there and
   does not work right :-(.  If memory falls short, you get zero filled
   pages instead of pages form the backing store.


OK, then, let me rephrase the question --- are there systems where
there's a shared memory mechanism that works, and mmap() doesn't?
