Not really. Use-once doesn't work for pages which are
or have been mmap()d, but later use of the cache will
not be able to put pressure on the pages which have
been taken out of the use-once loop.

Use-once as we have it now is fundamentally unbalanced,
I can't see a way of ever getting that thing to work
nicely.
