I have been analyzing the load that various X clients place on the host
machine and the network.  I have come across something a little odd in
GNU emacs.  In the file x11term.c, the function xfixscreen calls XNoOp
every time it is called (which is about once every .2 seconds).  I
compiled a version of emacs without the call to XNoOp and it appears to
function identically to the original.  I even tried severing the physical
connection between the client and the server (i.e. pull the ethernet
cable).  The only use I could see for the XNoOp was to verify that the
connection to the server was still functional.  This does not seem to be
the case however, because when the connection was severed the two
versions behaved identically.

Can you shed some light on the reason that XNoOp is being called?
