Thanks David, merely knowing about those 2 functions should get me
well on my way to having something working.

If I can use the above functions to run my embedded Stackless app in
its own sandbox then this becomes less of a problem. I was mostly
worried about the implication that everyone who uses Stackless uses it
as their main Python installation, which is a problem if it now means
I have to rebuild every 3rd party library I use for the myriad of
applications I have which don't need the Stackless functionality but
do require lots of pre-compiled libraries.
