...in the import processor. The contract of `RowSource.Next` requires that at most one of the return values will be non-empty. This wasn't the case here, and caused opaque failures in cockroachdb#58897. cockroachdb#58897 tries to enable background tracing by default, which for us means that the trailing meta can be non-empty (they'll contain span recordings). That behaviour ends up tickling this bug, tripping up TestCSVImportCanBeResumed. Release note: None
