---------------------------------------------------
I just got a failure with this patch after 44 iterations:
{noformat}
junit.run:

I was running without -Dtest.output=yes, alas :-(. Will run again with
-Dtest.output=yes.

> I'm seeing lots of the following failure. Seems like a flakey test (passes
> every so often).

> junit.framework.AssertionFailedError: client could not connect to

> I've found 3 problems:
> 1. QuorumCnxManager.Listener.run() leaks the socket depending on when the
> shutdown flag gets set.
> 2. QuorumCnxManager.halt() doesn't wait for the listener to terminate.
> 3. QuorumPeer.shuttingDownLE flag doesn't get reset when restarting the
> leader election.
