I know that this is possible, but the question is how common this
situation is.

If an application is hogging resources, you'll want to kill that
application, not X.

I think should be pretty clear by now that they can :)

Okay, now we're getting closer.  There's no reason you can't make wine
handle those situations more gracefully.  But really, if you're doing
highly experimental things like running windows games in wine, it's not
unreasonable to expect that you do the tiny amount of extra of work if
you want enable C-A-B.
