Perhaps not, but AFAIK it does swap programs to disk in order to 
increase the available memory for i/o buffers (just like that other 
operating system from Redmond).  If the swapped memory was still in 
the i/o buffer when recall was neccessary then it would be ironic 
but totally reasonable to recover the page from there.
