Review Comment:
As for preventing the race, I would have to probably wrap parts of code
checking and setting completion in synchronized blocks. Not sure if that would
impact performance. But it seems the race was there already (between the
timeout worker checking for a timeout and marking the future as completed
exceptionally vs the inbound handler thread marking the thread as normally
completed. Finally it's your call.
