Here the rest part of program, I did not think here can be any leaks, 
this is why I posted code without this part.

module Common
  def Common.post_it(link)
    begin
      puts link
      agent = Net::HTTP
      html = agent.get(URI.parse(link))
      doc = Hpricot(html)
      forms = doc.search "//form"
      forms.each do |form|
            puts form.search("input").length
      end
    rescue => err
      puts err
      file_write_safe("logs/errorlog.txt", "#{err.to_s}|#{link}\n")
      return false
    rescue Timeout::Error
      file_write_safe("logs/errorlog.txt", "Request Timeout|#{link}\n")
    end
  end

  private

  def self.file_write_safe(file,message)
    File.open(file, 'a') { |f|
      f.flock(File::LOCK_EX)
      f.write(message)
      f.flock(File::LOCK_UN)
    }
  end
end
