Me too. This test case seems much too far away from real world use
to justify diddling low-level locking behavior; especially a change
that is obviously likely to have very negative effects in other
scenarios. In particular, I think it would lead to complete starvation
of would-be exclusive lockers in the face of competition from a steady
stream of shared lockers. AFAIR the existing behavior was designed
to reduce the odds of that, not for any other purpose.
