If you stand back that far, maybe you can't see a difference ;-) ...
but the proposal on the table was for an extremely special-purpose
on-disk structure. I'd prefer to see first if we can solve a more
general problem, namely the fixed size of the existing lock table.
It's certainly possible that that idea won't work out, but if it can be
done for a similar time investment as the special-purpose log would
take, it'd be a win.
