      Description

      After adding a watchdog which shows the stack trace of blocked reactor callbacks, I see that in many cases it's actually due to blocking within glog itself. We should see whether we can use an asynchronous sink in glog to avoid this, or else we need to be more careful to move even more work off of reactors.
