SYS v version 2+ Message Queues facility...

[mitchell at LOCUS.UCLA.EDU]

I thought that I mailed this out earlier but I havent seen it yet on the
net so... here goes again.


Has anyone had experience with SYS V version 2 or 3 Message Queues facility?

I need an IPC facility for doing high speed I/O between processes and it seems 
that SYS V.2 message queues would be perfect.  

What is the performance like?  
Any limitations that are not documented?  
Any idiosyncracies?  
Any suggestions?
