ok, but... wouldn't this also force squid to rotate it's log files
(assuming logfile_rotate != 0) ???

Is there a way to _only_ restart the helpers ??

This seems to be a good idea, but... how would my external application
(the one that writes new data to the disk) know the PIDs of all the
helpers in order to send them the sighups ?

Would it work to send a signal to Squid and squid would propagate it to
my helpers... this could have 'negative consequences'

or is there some API in Linux that permits me to find exactlly the PID
of my helpers (by their name maybe) ???
