 Something like this, it return an array

   def load_server_list(filename)
      servers = []
      IO.foreach(filename) do |line|
         next if line[0] == ?# || line[0] == ?\n
         servers << line.chomp
      end
      servers
   rescue
      raise "Can't open #{filename} : #$!"
   end

 to use it

  servers = load_server_list("serverlist.txt")
 
 servers.size will give the same than $server_count
