OK.

I don't actually have a clue what you're doing here.  Restoring a
virtual machine from disk/network or something like that?

It might be appropriate to do a big memory-reclaim before starting the
operation, along the lines of suspend-to-disk - go off and allocate
(and possible pin) sufficient memroy for the entire operation before
actually starting it?
