There is activity on the helper when Squid asks it to shut down by closing
the write fd squid->helper.

Not relevant if the helper has ever been called. The write channel is
closed in helperShutdown() as you already discovered. This triggers the
helper to close the helper side of the read channel (by exiting) when
seein EOF on it's input, which causes helperHandleRead() to close Squid
side of the read channel.
