Addendum to log :
     When a page maps a Prototype PTE, we can't know if it must be 
deleted before dropping shared reference. Modify ASSERT accordingly.
     Restore the ASSERTion that only page fault should provocate the 
creation of the PDE and modify PDE refcounting in pageout code accordingly.
