Well, as far as I understand Jonas, not all sections are empty.  But
if there are too many empty sections on one page, no pagebreak occurs
and you get a big overfull \hbox.  Thus, I suppose that DPC's
suggestion to insert pagebreaks manually (\clearpage) is an
appropriate solution.

Ulrike, the reason Jonas [ab]uses \section is because this macro
contains discardable vertical space i.e., the space above the section
header disappears if the section begins at the top of a page.  This is
exactly what Jonas wants, hence using \section is appropriate.

Writing a dedicated macro is certainly possible.  But unless the
document is large or has to be revised in the future, inserting
\clearpage manually where needed makes sense.  I suppose that Jonas
needs a solution soon and is not interested in an everlasting reseach
project.

Jonas, does \clearpage, as suggested by David, solve your problem?

Regards,
  Reinhard
