DOCBOOK-APPS: Figures broken in half (kind of)

Hi

In the work that I'm doing i have to write several algorithms and I
decided to use the following markup:

<figure>
  <title>
  <programlisting>
    Algoritm
  </programlisting>
</figure>

I want to know if there is a way of preventing the algorithm to break
across pages?

I'm using dsssl with jade.

P.S As an alternative I would accept :

  do a
  do b
             (continues on next page)

----- page break ----
  
  do c
  do d
  done
