> Reducing locking in OveruseFrameDetector and increasing constness.
> 
> I also added a few TODOs there to see what we can do to reduce the chance of contention.
> To catch regressions, I've started using the ThreadChecker class on the processing thread but it might also be a good idea to add similar checks for other known threads such as the thread we receive frames on.  I'm sure we can reduce locking even further.
