Done, but it doesn't seem to have registered with cocoon.  However, 
going directly to qstat-jobs.html works.

However, qstat-jobs.html doesn't appear to recognize our host names or 
the load on the hosts.  It does get the architecture, status, type, 
number of slots, number of occupied slots and so on, correct.  I think 
at least part of this relates to the XML issues that have been 
discussed recently on GE-users.

Done.

Thanks very much for the help!

I may poke around in the xml-qstat innards myself, but can't promise to 
do that in a timely fashion, or to resolve any issues if I do so.
