That is significant.  In my case, I *had* to start a new interpreter in
order to guarantee that each execution of the script was running in a
pristine environment.  I made the mistake of assuming you had a similar
need.  (I also somehow assumed you were running on Windows...)

Just keep in mind that it is very difficult to completely "clean up" a
python interpreter and that there is the possibility that when you
launch a script it might be influenced by a previous script.  For
example, module attributes set by one script will likely be visible to
subsequent scripts.  As long as you are aware of that and it isn't a
problem for your application, life is much easier if you create one
embedded Python interpreter and allow it to live for the duration of
your main program.
