Tobias, I think that in this particular case, you're right -- we don't
need an exclusive repository lock to create a couple of tables and bump
the format number. But we're anticipating that future "svnadmin
upgrade" processes in future releases might need to do so; there may
be schema changes that don't require dump/load, but still are dangerous
enough to warrant exclusive access.
