The previous code assumed that if a condvar woke up spuriously, the status would be CVStatus::Timeout, but that seems wrong (doesn't match the WaitForAddress semantics, and wasn't guaranteed to begin with). Instead, guard shutdown completion with a variable. While at it, move the monitor outside the instances, there's no real reason it needs to be there.
