Ok.  I can't explain it.  There's no special treatment for guest stack 
pages.  The accessed bit should be maintained for them exactly like all 
other pages.

Are they kernel-mode stack pages, or user-mode stack pages (the 
difference being that kernel mode stack pages are accessed through large 
ptes, whereas user mode stack pages are accessed through normal ptes).
