Hmm ... a gig here, a gig there, pretty soon you're talking about real
memory? He's got several sorts and hashes that are each taking over
100MB according to the memory context dump, so it seems impossible that
it all fits into a strict 32-bit address space. There's surely no harm
in double-checking the executable's file type though.
