We don't actually seem to use NumEraseUnits, although I have absolutely no 
recollection _why_ not. But that would explain why we never bother to 
byteswap it. The code is intended to be endian-aware, although 
I've personally only tested it on LE machines, so I wouldn't swear that 
I've caught all cases.

It's been known, but I can't remember whether the person who asked me about 
it ever admitted to it in public.
