Yes, we liked such an approach earlier too and its conceivable that we
will run out of the 64-bits too :-)

But as Jon Corbet pointed out in the the thread above, it looked like
adding a new system call has been the "traditional" way of solving this
in Linux so far and there has been no consensus on a newer approach.
