This is what I did in Orbifold.py. It worked, but performance was not optimal and GUI response time could be slow. But again, this was with Visual Python running its own CPU-hogging thread at the same time.

what about calling csound::PerformKsmps() in a loop in the
csound thread? Would that allow the other threads to work in tandem?
In a single thread, could csoundYield() be used to give the GUI some
life?
