Hi Alex -

Thanks for the diagnosing the problem so completely and taking the time 
to bring it to our attention.  We will fix this issue for v8.2.0.

I created a ticket about this problem on the wiki here:
  https://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=4388

At the above URL, I described how we will fix the issue for the next 
release of HTCondor (v8.2.0), and also brain-stormed some potential 
workarounds that you may like better.

Hope the above helps,
regards,
Todd
