	I'm looking (very hard) for possible mechanisms of process
communication that could satisfy some fairly tight real-time constraints.

We are considering porting our Versados products to Unix or to some such 
Unix variant. We currently have Ultrix-32 and SunOS 4.1, and I have some
timing results for them. We will also have Solaris and OSF soon. Many 
OS vendors claim their product will have "increased real-time support"
in their next release, but we need to know what is currently available 
to make desisions now. 

BSD 4.2 sockets and System V messages are all we have tested, so we would
like to know if anyone else has done any studies on "real-time" Unix.
