Correct hyphenation of compound words (in languages that have special
rules for them) is AIUI something that can't be dealt with by an
unmodified Laing algorithm.  As a result, it requires something that's
not TeX, let alone `not current LaTeX'...

Petr Sojka has done some very interesting work in this area ... see
his papers on hyphenation in the last two EuroTeXs, and in various
issues of TUGboat.  I don't recall off-hand whether his work addresses
the split-doubles issue, but it's worth reviewing.
