   Ok, I think the original commit just surfaces a lingering bug in 
`ConcurrentQueue`. `UnsyncFront` is simply not safe, as it calls 
`deque::front()` which can be implemented in terms of `deque::begin()`, but a 
concurrent call to `deque::push_back()` is specificed as invalidating all 
iterators.
