Major Description
BalanceAfterCommsFailureIT does a SIGSTOP and then SIGCONT to simulate some network outage. It uses pkill to send the signals which will send that to any processes on the system matching "TabletServer".
This isn't really ideal (and I believe is actually error prone if there is a TabletServer running on the same node by a different user). Figuring out a way to target only the TabletServers running in the minicluster for this test is much better.
