Yup I think that's the biggest.  And you can do it fairly precisely with null
locks... at the destination   and in some sense reserve the destination before
you actually move something to it.

...but, and I don't know if it's important,... but if you move locks during a
MOVE, locks within a moved tree are retained.   But if we don't support moving
of locks, some locks might be totally destroyed by the MOVE operation.  I think
that's what the previous proposal said.  It's hard to recall.  My brain has been
warped by the new proposal.  :-)

...I think it was/is also the hope that tying locks to resources (Judy's
proposal) provides a simpler model and that that will pay off in other ways.  I
think the jury's still out on that.

Anything else?...
