If you do this, you need to do the check in pre-revprop-change too, because revprop changes don't call start-commit; and also in pre-commit, in case a commit-in-flight is currently uploading data — has passed start-commit but not yet called pre-commit. > That said, based on the approach you are taking, I do not think you need to > do any of this.
