Alain,

thanks for looking into this.  My boss, Keith Jackson (you may remember 
me from Condor week), is not too concerned about the performance 
"problem", although I was hoping to speed
up negotiator cycles so our workflow GUI can run demo DAGs fairly quickly.

From your message it sounds like the DAG behavior I've described might 
be changed- so that it won't trigger negotiator cycles, making jobs run 
even *more* slowly
than they do now.

One thing that occured to me is that for our demo GUI purposes, it might 
be convenient for us to have a way to trigger negotiator cycles 
externally.  I'm going to poke around
the manual to see if I can do that.  i suspect it's possible but just 
not documented.
