dd apparently cannot actually create files with sizes that can't be fit in a
64 bit number?
I'm not sure if that's a dd limitation or this 3.11 kernel and ext4
filesystem.
JUST RTFS'd and dd is using off_t which I'm guessing based on the 16/15T thing below is totally not
anything to do w/ dd. 0xFFFFFFFFFFF for some reason.
The unrecognised prefixes thing, and the memory exhaustion, might maybe
possibly be interesting?
