It risks something swapping over the data before savevcore gets it.
However, if we can come up with a way to reliably notice if that
happens, I think it would be a good option to have available, for cases
where (a) the dump partition is _not_ used for swap or (b) the admin
specifically chooses to run that risk for the sake of faster boot times
(something I can certainly understand, especially since in more and
more cases machines have so much core compared to their workload that
actually paging anything out to swap is extremely rare).
