Seymour Cray thought that virtual memory in general was a bug. Anything
that got in the way of raw performance (including hardware address
translation and memory protection) was not allowed in his machines.
FYI: The standard amd64 kernel sets MAXDSIZ to 8gig. If you need more
then you need to add
option "MAXDSIZ='((paddr_t)16*1024*1024*1024)'" # 16 gig
process space...
to your kernel config file and rebuild/reboot.

(still wondering how I went from 56k on LSI-11s and 4meg on 686s to
32gig on FX-8350s...)
