No, stop won't return immediately. It waits for the control process to
stop, but it waits for a limited amount of time. So when stop returns to
restart, squid may still be alive. That's why I propose using the stop
function own return code on restart: if stop says it returned by
timeout, restart shouldn't start.

I guess the script removes the pid file because squid may have been
killed without a change to clean after himself. Other CentOS init
scripts do the same.
