Do we care? You can't do partial updates to objects IIRC, so many writers pretty much has to be wrong somehow or other.

Implementing #1956 would solve this issue, and would make the entire atomic scheme simpler.

A fix for that was already pushed (backing off when identifying a race in atomic write scheme). However, a more complete solution in which we provide a different atomic access scheme (#1956, #1847) is imminent.
