How can you restart a flow graph after a head block kills it?
For example, I want to do something like the following:
tb.start()
tb.wait() # head block will terminate
... do some reconfiguration ...
tb.start()
However, I get a seg fault if I ever try to call tb.start() after the head block returns.
I take it a flow graph isn't reusable after a head block terminates?
If I remove the head block:
tb.start()
tb.stop()
tb.wait()
tb.start()
Works just fine. Could someone explain what is going on or point me to the documentation (having a hard to finding anything useful in the documentation).
