Broken in Changset 1082, though that is pretty obvious from the commit log 
itself.

I believe that this is a more likely implementation of CircularBlockingDeque:

 - peekFirst returns null if there isn't anything in the queue, which is something that FrameTransformTree seems to expect
 - addFirst moves the start "backwards" one so that it continues to satisfy the structure invariant
