You can consider this a temporary implementation detail. I'm thinking
of making the tests print their logs via a single fd if the runner is
executing them, making all that sentinel business unnecessary.

Having the runner consolidate the logs and handle the log buffering
would also make it possible to grab the debug prints from
incompletes...
