Getting "DeadReferenceError: Calling Stale Broker" after ipcontroller restart #9
Description
Original Launchpad bug 308253: https://bugs.launchpad.net/ipython/+bug/308253
Reported by: vvatsa (Vishal Vatsa).
Not Sure that is a bug or an expected behavior.
I am starting the ipcontoller such that it reuses the ipcontroller-tc.furl between restarts.
After the restart, if I invoke a DeadReferenceError with the following traceback:
I am using the blocking TaskClient from an ipython shell.
In [8]: tc.spin()
