Justin Karneges reports this bug via e-mail:
We encountered an issue where Whack's socket read thread will end, but no component reconnection is made. The connection is still open, just not being
read from anymore. (...) Make sure that any exception thrown during socket reading does not leave the component connection in a weird state. Either the error is non-fatal, and everything should continue normally, or the error is fatal, the socket should be disconnected and reconnected as normal.
