Subject: trapping TERM in a daemonized (Daemon gem) script

I'm using the Daemon gem, and I'd like to trap the TERM signal so that
I can have graceful termination of my main execution loop:

$running = true;
Signal.trap("TERM") do
  $running = false
end

while($running) do
  #some operations that could take a few seconds
  sleep(5)
end

However, I get some memory errors when I stop the process, and I can
sometimes get an extra process after a 'restart' is issued, that I
can't kill with a 'stop'

I looked at the source to the Daemon gem, and it warns not to trap the
TERM signal in your script. So how can I gracefully end my loop if I
don't trap TERM?
