Hi Kevin,

If the above satisfies your needs, great.  But just wanted to point out 
you can do the same thing (drain a node gracefully) with the 
condor_drain tool.  Do "man condor_drain", or see
 http://htcondor.org/manual/v8.4/condor_drain.html

Also in the upcoming HTCondor v8.5.6, the condor_drain functionality is 
exposed via HTCondor's Python API. :)

regards,
Todd
