If you want to stop a running flow graph you must not wait() for it first. 
wait() waits until either it is stopped or it completes naturally. Thus, you 
want this order of operations:

  tb=top_block(options,0.8)
  tb.start()
  sleep(5)
  tb.stop()
  tb.wait()

The wait() occurs last so that what it is waiting for is only for the stop() to 
complete, not for anything else.
