I have responded on that thread to see if Noah can have a look and
decide if it would be worth back-patching cc2c7d65fc.
There have been other changes in this area (e.g. removing
durable_rename_excl) so it would be good to know if back-patching just
cc2c7d65fc will work.
Kyotaro, since you can reproduce the issue would you be willing to test
that?
