And doing "our own swapping" has the distinct advantage that while 
clicking on a packet (which was reassembled and requires some 
non-trivial amount of I/O to access) might be slow sometimes, the rest 
of the UI--and indeed the rest of your computer--remains functional, 
something that can't be said if you're swapping heavily.
