Well, I'd say add a #define to deal with this and define it if the
installed Python is good enough.  If that is hard to do, i.e. checking
the version of Python/running "import thread" etc., make an option
called VTK_USE_PYTHON_WITH_THREADS or something like that and ask the
user to set it if they want it.

Charl, thanks for taking a look at this threading stuff.

cheers,
