tl;dr Yes, the connection is unusable by the client, but the Accumulo code
should retry that implicitly.
Expanded: After running my hacked-together `fastHalt` code to a
TabletServer which didn't yet have its lock, I then made a call to
`authenticate`. The call to `authenticate` fails with a `TTransportException ->
IOException`. As such, `ServerClient` should implicitly catch and rerun the
operation after a brief pause -- exactly what we want it to do.
