> TestQuorumJournalManager can occasionally fail if two consecutive test cases pick the
same port number for the JournalNodes. In this case, sometimes an IPC client can be cached
from a previous test case, and then fail when it tries to make an IPC over that cached connection
to the now-broken connection. We need to more carefully call close() on all the QJMs to prevent
this.
