So this patch adds protection against "two of the same kind
simultaneously". How could we check it's complete?
Have we pondered the more general problem of which "operations"
(whatever that is) exclude each other?
Good point. For what we want now, I think these extra checks are not
required. I think these could be added in a separate series if any.
Planning to drop it for next revision but the discussion is still open.
Thanks,
