#2198: Polipo cron task returns with exit code 1 if Polipo is not running
-----------------------+----------------------------------------------------
 Reporter:  sjmurdoch  |       Owner:  erinn      
     Type:  defect     |      Status:  new        
 Priority:  normal     |   Milestone:             
Component:  Polipo     |     Version:  Polipo: 1.0
 Keywords:  haspatch   |      Parent:             
-----------------------+----------------------------------------------------
 The Polipo cron job to reload the forbiddenFile and config file tries to
 not send a USR1/2 signal to Polipo if the PID file cannot be found. A
 side-effect of doing

 {{{
 [ -f "$PIDFILE" ] && kill -USR2 $(cat "$PIDFILE")
 }}}

 as the last line of a shell script is that if $PIDFILE does not exist, the
 shell script with exit will return code 1 (the return code of the last
 statement executed: `[ -f "$PIDFILE" ]`).

 This occurs when Polipo is installed, but configured to not run on
 startup, and will cause cron to send an email to root.

 I am using Polipo 1.0.4.1-1.1 from Ubuntu Maverick.
