Ben Ingram 9468976c1d Don't try to map all resident pages to newly allocated VTs. Too slow, especially for large VTs ...

- Instead, keep VT cached for a few frames after they are deleted, this way they can be re-used if they're deleted/recreated due to state changes
- This should solve the problem of material changes causing pages to become unmapped for a few frames
