Intermittent test failures
The supervisor tests seem to fail intermittently. This is almost certainly because the tests rely on ordering guarantees that the CH doesn't really offer - viz ordering between multiple producers and 1 test case process, or ordering of monitor notifications - yet we should try to do something about this.
It seems easier to provoke failures by running with +RTS -N1

Another failure I've seen lately:
This appears more frequently since adding SystemLog support to Supervisor.
