Sigh.  However, I did write code allowing processes to share memory
without using mmap/munmap.  I wrote this for 4.2, but we've gone to 4.3
and I don't have the 4.2 code without groveling through *lots* of
tapes.  If anyone is interested, I can describe what has to be done or
maybe send out the code (I'd have to check some things, like, how much
is really 4.3 code I reused for the purpose).
