There was a problem hiding this comment.
use of truth here feels gratuitous since assertTrue is simple and obvious

If CPU is overloaded, it's possible that the stream doesn't get started after idle timeout. In this case, innerController is not set and innerController.cancel() will throw NPE. The NPE is caught in
run()and watchdog will still behave correctly, but the exception could be confusing. Adding a check to skip cancelIfStale to avoid the red herring.
