If I remember that correctly, kill SIGTERM and SIGINT will tell squid processes
to exit gracefully.
Certainly kill SIGKILL will kill them forcely.
When receiving SIGTERM and SIGINT, the parent will kill a TERM to its child,
wait for child to exit (surely it's the time after child has finished the
current request handling), then parent exit gracefully.
So most time you just need to say kill `cat squid.pid` and squid will behave
correctly. This is what "squid -k shutdown" does?
use kill -9 `cat squid.pid` or "squid -k kill" to kill them forcely.
See also man kill under un*x.
