@pmevzek @landley @jschauma @ryanc @0xabad1dea still, a #64bit #AddressSpace would've been more than sufficient as we can see by the fact that /64 is the default #IPv6 allocation for basically any consumer connection.

A #128bit address space is quite inefficient given we ain't saturating even half of it.

#ZFS does have that problem, abeit #Sun engineers at the time expected #64bit to be as quickly deprecared as #16bin and #32bit.
