VAX/VMS got there first! The origins of the NT kernel as written by Dave
Cutler and team of RSX11 and VMS fame mean that NT has quite a few
VMS-alike features under the skin.
The division of the 4G address space between system and process is the
same principle as VMS.
My goodness though, call me an old'n but I never really thought we would
be pushing the 4G limits in the same way as once upon a time there was a
640K and even earlier 64K limit :-)
