Theoretically, it could quite possibly work (I would have to think carefully
about all corner cases, but there's no deep reason it wouldn't work), but
practically, I don't see much benefit.  Current code simply depends on
the well tested _svmf_halt_if_requested().  Adding custom code for such critical
and difficult to write correctly code (even though it is short, it is very
tricky) is not something I look forward to. :-)

It also makes the state diagram simpler.  [Yes, I know, I have not written
it down, and my ex-supervisor almost killed me when I made a 1+ hour presentation
to the Sable group about this stopping the world business, after my thesis was
accepted without having written anything about it... ;-)]
