If you are ok with the flowgraph blocking your current thread you could
call `run()` on the top_block. Or you could continue doing other
calculations on your data after calling `start()` and then call `wait()`
on the top_block. `wait()` will either block until the flow graph is
done or return immediatly if the flowgraph was done already. In either
case you can be sure the flowgraph is done.
