Maybe we should discuss this before you sit down to write and text the
code.  Pushing things into the environment has its downsides: those
environment variables then affect all the subordinate processes,
including their children, grandchildren etc.  This is not always
wanted.

One alternative to environment variables would be detecting whether -P
is supported before the first time we invoke Python.  We do similar
stuff for Grep and other programs we invoke.
