Description

When processing the sync of object deletion, we use an If-UnModified-Since precondition to avoid deleting the local copy of the object if it's changed since the other zone deleted it. Data sync does not handle the ERR_PRECONDITION_FAILED error for this case, though, and treats it as a failure to be retried until success. This results in a data sync shard that gets stuck and can no longer make progress.
