Yes I remember smartdisk for DOS, I also remember the mess it used to make 
of some bigger applications under Windows 3.x (Lotus123 and Ventura spring 
to mind).  My point wasn't that the Linux kernel does anything particularly 
new that Windows (for instance) doesn't.  My point was that different 
operating systems manage their RAM differently.  I've actually written a 
memory manager in C for a real operating system - I'm not making this stuff 
up.

Windows memory management is pretty poor for the most part.  Linux works 
well compared to Windows. Linux compared to Solaris when paging under heavy 
load, really shows the advantages of Solaris' memory management (and I/O 
subsystems in general).  Horses for courses.
