Description

Didn't spend a lot of time investigating, but from the code it looks like we shouldn't be calling it after false at least on this path (after false from next, pushRecord returns false, which causes fetchDone to be set for the tag; and fetchOneRow is not called if that is set; should be ok unless tags are messed up?)
