humm... with moving of 1000's of headers... I wonder what the limit
will then be needed ?
also, that must impact gerrit too. iow I would need to increase that
parameter on the gerrit side
so that cherry-picking works ? or do we want to consider that for
these few transient patch that will need cherry picking accross the
move, people should manually rebase theses patch are re-push them to
gerrit ?
