Agreed, I've seen Windows services, etc, continue responding after "Windows"
is well and truly dead.

There's no implementation in the kernel... the closer analogy is that it's
like using a *ix in single-user (well, process) mode. You lose the machine
because there's no real parent environment to return to.

Windows Terminal Services is another example - you can fubar your session
without affecting others - though my experience is limited, I've never seen
a terminal user bring down everyone/other people's sessions... and in this
regard, there's a similarity with Unix.
