:Thinking about this a bit more....
:doesn't each process ahve it's own PTD?, so a process could sleep and
:another could run but it would have a differnt PTD
:so they could change that PTDE with impunity
:because when teh current process runs again it get's its own 
:ptd back again..

    Hmm.  Ok, I think you are right.  APTDpde is what is being loaded
    and that points into the user page table directory page, which is
    per-process.  So APTDpde should be per-process.
