I'm looking at csndsugui.py from filemix git, and it has a set_timer
method that uses gobject.timeout_add to schedule a future timer event.

Also in csndsugui.py it uses csnd.CsoundPerformanceThread, and looking
at csnd.py there is an isRunning method for that class.

So to discover if "an already-playing csd has finished", it seems you
may call CsoundGUI.perf.isRunning() ... if the return value is False,
then the csd has finished.  I guess.

There is also a GetStatus method, and perhaps some sort of way to
request that a function of yours be called when the performance ceases.
