But what in case if there is no activity on the helper?
There is activity on the helper when Squid asks it to shut down by closing the write fd squid->helper.
If we have N redirectors, then there is the chances than some of them will never called , isn't it ?
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.
