To people with shell access, especially Shai: please note that the
force(0) in Setup.php is there for a reason. Just because a query is
slow doesn't mean you can send it to Ariel. It also has to be acceptable
for the data retrieved to be seconds, or quite often, several minutes
out of date. This is most certainly not the case with the link table
select statements, which cause link table corruption as it is due to
being non-locking.
