> When the emitter reaches the max timestamp for the current queue, it stops
> emitting and waits for the max timestamp to advance. Since it simultaneously
> selects the next queue as the new "minimum" queue, it may deadlock if the
> previous min queue represents the new global lower bound after the max
> timestamp advanced. This occurs very infrequently and we were finally able to
> reproduce.
