I didn't say it was ;-). What I *am* saying is that if we're going to
do anything about this sort of problem, there needs to be a
well-considered system-wide plan. Arbitrarily changing the locking
rules for individual operations is not going to make things better,
and taking exclusive locks on whole catalogs is definitely not going to
make things better.
