Andre Gunther had a look during GSoC a few years back.
It is a pain. Windows does not trigger the exception handler
if it thinks the segment registers are wrong, so 9vx cannot
handle its own page faults. I think it might be possible to
structure 9vx as two processes, one operating as a kind of
debugger process attached to the main one, and have the
debugger process grab and redirect the faults, but it seems
like a lot of work.
