Subject:   Overflow in vm.vmtotal expected when allocating huge amounts of memory?

Are overflows in the vm counters expected when dealing with huge
amounts of memory on 64-bit platforms?  I wrote an application which
malloc'd 10TB memory and then sat doing nothing; vm.vmtotal showed
-2132654356K.  Shouldn't unsigned integers be used for any vm stats to
avoid overflows?
