I haven't looked at the existing sweep implementations, but it would
be unfortunate if sweep functions were not available that create at
least the same number of keys, or possibly more, for the purposes of
sweeping. I suppose there are different levels of emergency, where
perhaps you want to sweep all at once in a single transaction and lose
out on (already nebulous) privacy benefits. I say nebulous because
broadcasting a bunch of transactions all at the same time during the
sweep can compromise privacy even when the transactions have no common
ancestor outputs.
