Alright, another idea, but a PITA to implement.  This should be portable and
give us the kind of low-level control we need to get correct behavior. 
Basically we implement the pipe's read/write buffers as shm segments protected
by mutei.  Then the server can just maintain the data stream internally as a
list (or pair of lists for duplex).  Huge PITA, as we'll have to make files for
each pipe instance so we have something for ftok(), but should work.
