Pages should be marked busy only for some special occasions, wired pages are not
normally busy; the correct explanation is quite a bit longer than this, the
comment in the code explains VPO_BUSY as "page is in transit".  Right now this
flag doesn't seem tom affect vboxdrv code but it may lead to surprises when some
parts of code that are incorrect now are re-implemented properly:
