"reject and nullify the current lock promise" and tasks

[annevk]

I don't really understand why this queues tasks, until I saw that it also had an "in parallel" caller. However, that caller should probably queue a task to run this as this algorithm inspects document state that's not going to be available in parallel, right?

Right, yeah, it's going to parallel too early. I'll try to fix it up...
