Comment (by essandess):

 By the way, I have noticed a lag of a few seconds for squid to write the
 PID file:

 {{{
 $ sudo port load squid3
 $ ps -ef | grep squid | grep -v grep
     0  2971     1   0  9:25PM ??         0:00.01 /opt/local/bin/daemondo
 --label=Squid --start-cmd
 /opt/local/etc/LaunchDaemons/org.macports.Squid/Squid.wrapper start ;
 --stop-cmd /opt/local/etc/LaunchDaemons/org.macports.Squid/Squid.wrapper
 stop ; --restart-cmd
 /opt/local/etc/LaunchDaemons/org.macports.Squid/Squid.wrapper restart ;
 --restart-netchange --pid=fileclean --pidfile
 /opt/local/var/run/squid/squid.pid
   504  2976  2972   0  9:25PM ??         0:04.10 /opt/local/sbin/squid -s
 -N
 $ cat /opt/local/var/run/squid/squid.pid
 cat: /opt/local/var/run/squid/squid.pid: No such file or directory
 $ cat /opt/local/var/run/squid/squid.pid
 2976
 # the correct PID file appears a few seconds later
 }}}

 Could this PID file lagginess be related to the underlying problem?
