Avoiding Alarm Clocks While Spidering

Hi All:
  I am currently running a spider program derieved from an open source
Search Engine program call SWISH-E, the spider.pl file that I am using uses
the LWP::RobotUA class.  Now, the way I have it set up is that I have a
program that would prep the spider program with a list of sites to spider,
the the program would call the spider using the backtick(``).  From there
on, the spider becomes a zombie program, outputing results to a local
textfile for me to review later.  The problem I'm running into is that it
seems like the LWP class has a timeout function implemented that would sleep
the process after a period of time with a message saying "Alarm clock."
What is happening is that, since my process is a zombie, when it is put to
sleep the system kills the process.  Is there anyway around this situation?
Is there a command or flag in LWP::RobotUA that I can set so it would not be
put to sleep.  Thanks in advance!
