    Yes, it works in 33-rt, but the way it's implemented is a horrible
    hack. I had not enough capacity to implement that cleanly for 3.0-rt,
    so I simply dropped it for now. The preliminary patches are there
    (mainly distangling the disable_pagefault logic), so it should not be
    that hard.

    Thanks,
