that sounds troubling.  the published claim is that we generate about
twenty times faster now than things used to be.  do you have any kind
of comparison data (actual timings, edge counts, whatever)?  where is
the time spent currently?  if you provide the grammar and a pointer to
an earlier LKB version that you know worked faster, i would be tempted
to try and investigate this further.

yes, in fact i think it would be useful if we all made it a habit to
email `developers' whenever we do something potentially relevant.  how
do others feel about this?  i realize ann and i are currently filling
up quite a number of mailboxes, but myself i am typically content just

people are currently up to ...
