I'm still not very happy about this, mainly because it seems like
(a) it's papering over just a small fraction of the true problem
and (b) there's been no discussion about cost-benefit tradeoffs.
What's it going to cost us in terms of additional locking --- not
only performance, but the potential for new deadlock cases ---
and does this really fix enough real-world problems to be worth it?
