Runs a guarded-write procedure call and returns the affected-row count it reports. Every work-queue write is a
stored procedure whose single result set carries AffectedRows (SELECT @@ROWCOUNT AS [AffectedRows], plan 12 /
CD9); the count is the fence's arbitration signal, so a missing result set reads as zero rows changed.
