It would also reduce the severity of the deadlocks occurring when a process gets stuck on a parse or dies in the middle of it: instead of deadlocking, the other processes would just display stale versions instead of wasting time. If we design these parser cache locks to expire after a few minutes or so, it should work just fine.
