And a few pages can make a difference on _any_ device, not just an embedded
system. For a purpose specific system, that can be the difference between
fitting the working set in memory and having to hit swap space.
No one has proven any memory savings yet, so why are you saying this is
noticable?
I didn't mean to imply that the VT subsystem itself was necessarily
responsible for any space savings, I simply intended to point out that
savings of a few pages can make a difference.
On that note though, I think I've got something that should work to
check this across a couple of different configurations, so I'll
hopefully have results soon.
