Does your flowgraph in tb naturally stop? The tb.wait() is a blocking
call and will halt the main loop there until all threads (blocks) in
tb are done. If your flowgraph doesn't have something that stops
execution (like a finite file or a blocks.head block), then it will
continue to process forever and your tb.wait() will continue to block.
