Remove length prop on NextTickQueue class. We technically don't need to keep track of the length of the queue in two places as we already have tickInfo doing that work (between the index & the length we have enough data for everything). Store asyncId in a const within the _tickCallback function. Accessing Symbol properties seems to be quite a bit more expensive than string keys so this actually has a decent performance impact.

Were the perf benefits in this high enough to backport? |
