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.
