Convenient when you want to create a fresh cluster
each test run: just pass --create and you'll get
a cluster with the right number of daemons for
the tests you're running.

Previously this could get hung up if we killed one
PID and then the daemon reappears with a different
one (perhaps because we caught it during
daemonization?)
