[Stephen J. Turnbull]

By the way, Aditi is my student under the Systers org.  Please take
good care of her!  Thanks to Simon and Aditya for getting started
already! :-)

I would recommend that you have two full suites locally, something
like

gsoc2016 -+--- gnu ---+- mailman
          |           |
          |           +- mailmanclient
          :           :
          |           +- bin, include, lib for venv
          |
          +- systers -+- mailman
                      |
                      +- mailmanclient
                      :
                      +- bin, include, lib for venv

This will allow you to configure each suite appropriately.  The
systers venv at least, and possibly the gnu venv, should *not* use
--system-site-packages, so that you can have private and fixed
versions of external packages like Falcon and Django.  This will cost
some disk space, but measured in 10s of MB I suppose.
