I'm rewriting some old Python scripts in Ruby. Just to learn a bit more. 
I want to thread this code to check websites concurrently. Could somone 
offer advice? What are reasonable limits on threads in Ruby?

    ips.each do |ip|
        begin
            Timeout::timeout(5) do
                Net::HTTP.start(ip) do |site|
                    data = site.get( '/' ).body.downcase
                    if data.include?(minolta) and 
data.include?(pagescope)
                        puts printer + "\t" + ip
                    elsif data.include?(xerox) and 
data.include?(printer)
                        puts printer + "\t" + ip
                    else
                        puts "website\t" + ip
                    end
                end
            end
        # Don't really care about exceptions just time outs mostly.
        rescue Timeout::Error
            puts "Timeout\t" + ip
        rescue Exception
            puts "General Exception\t" + ip
        end
    end
