Answer status to the client that asked, not everyone

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.
