`callback` is not defined in "process the lock request queue queue"

10. Enqueue the following steps on callback’s relevant settings object's responsible event loop:
    1. Let r be the result of invoking callback with a new Lock object associated with lock as the only argument.
    2. Resolve waiting with r.

But there is no variable named callback in this algorithm. I guess each request needs to store its callback in it.

Yep - likely a refactor didn't capture that.
