A bit of MSDN browsing revealed that Microsoft has already "fixed" the
vulnerabilites, despite the claim that this was impossible.  The
concepts are called "window stations" and "desktops", and there is
plenty of documentation.  Everything is there: separate sets of hooks,
separate message queues, and so on.

Maybe there are some flaws, but the overall design seems to be sound.
