The latency for interactive stuff is definitely more noticeable though, and

more tightly with the VM - we've already decided there which apps are
"interactive" and thus need low latency ... shouldn't we be giving a boost
to their RAM pages as well, and favour keeping those paged in over other
pages (whether other apps, or cache) logically? It's all latency still ...
I like this idea. Maybe make it more general though--tasks with high scheduler priority also get
more of a memory priority boost. This will factor in the static priority as well as the
interactivity bonus.
