Hey man, this is what I did. If you can extend PDF::Writer that class or 
just open that class up, then you can add this function. If the markup 
comes out horrible, look at http://gist.github.com/224821

<pre>
  def wrap_it(&block)
    new_pdf = ConsoloPdf.new
    beginning_y = new_pdf.y

    yield new_pdf

    new_pdf_height = beginning_y - new_pdf.y

    self.start_new_page if self.y < new_pdf_height

    yield self
  end
</pre>
