There is something more I don't understand: if you take the following 
example:

\hsize=2cm
aaaaab\discretionary{1}{2}{3}\penalty-10000cd

\hyphenpenalty=-10000
aaaaab\discretionary{1}{2}{3}cd
\bye

(with pdfTeX), hyphenpenalty seems to be something more than just a 
penalty after the discretionary. The question is: how is it possible to 
set it with nodes? Discretionary nodes don't have a "penalty" field (not 
in the manual at least)...

Thank you!
