6. Perhaps don't use the LRU pagevecs for large pages.  It limits the
   severity of the problem.

I think that makes sense. Being large already amortizes the cost per base
page much more than pagevecs do (512 vs ~22 pages?).

We try to do this already, don't we? Any spefic case where we have THPs on
pagevecs?
