OK, the lock management strategy appears to be safe (or "correctness
preserving under this transformation").

What about the queue management for things needing deltification, in
case it's run less often, and the queue builds up enough that the
next scheduled run starts before the last completes? Manage that
(I'm sure you can, you're such a clever boy!), and I'll feel better.

Interesting claim ("where it would help most"). I fear the
determination of how much deltification helps in any given case is
considerably more subtle than mere size.
