Doesn't the work around context cancellation happen asynchronously? Given that we immediately send SIGTERM won't it be non-deterministic as to which stuff actually sees the context cancellation?

"run" won't return until it and all its child goroutines are complete, at which point there shouldn't be anything still running. This is actually an improvement on the previous behaviour, which listened for a signal and immediately ran kill + exit.
