After updating Akka from 1.2.3 to 1.2.4 one of our tests went haywire. Endless loop of "timeout await for agent: driver-conductor. Retrying...".

It's not reproducible every time but failed several times in our nightly tests.

Here is the test and the problem is in the shutdown after the actual successful tests: https://github.com/akka/akka/blob/master/akka-remote-tests/src/multi-jvm/scala/akka/remote/artery/AeronStreamConcistencySpec.scala#L89-L91
