In order to keep the gui viable, ecasound runs in a separate thread.  In order to keep the program from getting ahead of itself and trying to launch ecasound before the current recording process has finished, I use gobject.timeout_add() for the length of the recording (plus a second or two for safety).

More specifically: are you sure you need threads at all?!
subprocess.call will block the GUI, but subprocess.Popen won't.
