In daemon mode fetchmail will only allow one process per user anyways. 
So if you try and start a second one it just wakes the current process
and grabs the mail.  From the man page:

       Normally, calling fetchmail with a  daemon  in  the  back­
       ground  sends a wakeup signal to the daemon, forcing it to
       poll  mailservers  immediately.   (The  wakeup  signal  is
       SIGHUP  if  fetchmail  is  running as root, SIGUSR1 other­
       wise.)  The wakeup action also clears any  `wedged'  flags
       indicating  that  connections  have  wedged  due to failed
       authentication or multiple timeouts.
