Is this more like what you need?

trap "ALRM" do
    puts "Look's like we've worn out our welcome. Goodbye!"
    exit
end

Thread.new do
    sleep 5
    Process.kill "ALRM", $$
end

puts "Waiting for the fun to start..."
i = 1
loop do
    puts i.to_s
    i += 1
    sleep 1
end

...or do you definitely need to catch the SignalException within your main code?
