status is a terminal event. Broadcast, the healthcheck's answer ended any ipx fetch that was watching a scan, which stopped reading at the next probe while the scan carried on. It could not happen while status waited behind the scan; answering it at once made it happen every 30 seconds. Each connection's writer now takes private replies beside the broadcast, and the test checks another client hears nothing.
