I was just discouraging people from arguing about whether locks should
be breakable or not, that's all. :-)

The lease-based model sounds like it may be very useful. Nobody is
closing the door on that idea. When the community sits down someday
to actually start implementing locking features (post-1.0), we'll
definitely re-discuss everything, including your idea. That
locking-plan.txt isn't the gospel; it's just a "capture" of previous
discussion.

But at the moment, we're all gunning very hard toward 1.0, and aren't
discussing or working on new features. That's the only reason you're
not getting a huge groundswell of reaction at the moment. It's not
that anyone is against lease-based locking, we're just not thinking
about locking at all right now. We're closing 1.0 bugs.
