After reading this, I'm wondering if virtual memory isn't the culprit. 
When you close a document, the area of memory that "held" the document 
isn't immediately cleared, thus the document may still be in use. The 
advantage of doing this is that if the user closed the document by 
mistake, re-opening is instantaneous.
