Unfortunately, I don't think that that can be done in a reasonable
way. It would have too many other side effects that people would
complain about and wouldn't be useful for much.
Probably the right way to do this is to _not_ make the script a tla
subcommand but rather just to add a new administrative interface.

No, and, it would be icky.
The simplest way to do it would be a single global lock but of course
that would hork concurrent commits. You could do it with a fleet of
global locks, but that'd still slow down commits, cause problems if a
single archive spanned multiple devices, make archive permissions
harder to manage, and add a confusing new set of states in which you'd
sometimes have to `lock-revision --break'. Just not worth it for
this one little thing.
(Of course, it'd be handy for the long sought-after
changestamps-to-speed-up-mirroring to, but, still, costs v. benefits
-- not worth it I think.)
