Not sure of the strace controls myself. But that trace has already been
of some use, that process was doing nothing but idling along waiting for
some network traffic to arrive.

Time to look at any other squid processes around and see if they are
doing something.

The parent process can be expected to be idling also waiting on signals,
or doing nothing at all. Any others ...
