:I mean does msync() preterb the LRU order, by counting as
:a recent use? It's probably wrong to preterb the order,
:since what you are doing is forcing pages *out*. If you
:want them *out*, then they probably have lower locality
:than the pages you decided not to force out.

:In other words, msync() should probably not change the
:LRU order.
