This is a tiny change I found while pruning my local branches, and I wouldn't want us to miss it.
The guard on
atomic_batchis utilized a lot, which - in the current setup - also causes the guard oncheckpointsused in theatomic_checkpointmethod to be in force significantly longer than necessary.This tiny change with no impact on logic fixes this, as confirmed by guard lifetime measurements in a
--devrun; the maximum guard (oncheckpoints) duration is reduced by ~75%.
