Hmm. The NeWS image bounce is running entirely in the server.  I was
thinking more of operations that involve client-server data transfers.
Is it possible that I am not seeing any improvement because I am limited
by the bandwidth of the client server connection?  The timings I have
are for a fairly large image (512x512) and it is noticable that it
appears in 3 or 4 chunks. What sort of bandwidth should I expect for
a UNIX domain socket on a SPARCstation 1?
