To be fully honest, I knew you were going to say that! :-P It's just,
with the code looking like it does _before_ your patch reworking the
host and guest capabilities, I still liked my approach more, and that's
why I decided to give it a try!

With your patch (the one in [2]) in place, I probably also think that
making this a "proper function" returning an int.

I think I like it, and I can certainly rework this patch one more time
on top of yours. Apparently, this patch seems to suffer from some
particular bad luck, since I'm going on vacation for ~2 weeks, so such
rework and repost will be delayed some more time. :-P

Anyway, thanks for having a look at it. I'll respin the patch as soon as
coming back to work.
