Rik, here's yet another item for the wishlist on your new VM. :)
Device drivers really are a special case because they typically need
their memory at short notice, and at awkward times (such as in the
middle of interrupts). What sort of flexibility do you have regarding
the allocation/release of the buffer pull in your driver?
