we are having similar problems with RedHat enterprise.  They are
particularly bad on older systems but even my new fast computer
occasionally goes nearlky catatonic while trying to do X-Windows
things esp the AIPS TV.  We have found that tv=local on the command
line helps (unix sockets seem faster than internet), but our systems
people are still trying to find what is wrong.  Occasionally a build
of the OS seems better but when they repeat it, it seems the same
again.

I keep hoping some cure will be found.

Note that if you fill 2 xterms with text and then grab one and move it
around in front of the other, you will see that the background xterm
is very sluggish updating the text in the window.  It is X-Windows and
interupts etc that are interacting - but as usual AIPS triggers the
issues worse than most things.
