Since, in practice, the waitlist is the only area that's touched frequently, I
don't think the lock is going to come under contention very much even with
only a single shared lock. Maybe your patch is an improvement but I don't
think this is the right time for it.
Let's concentrate our efforts on finding and fixing real bugs for the time
being.
