Hi William.  There is a limit to swap that a modern Linux system can use 
but it is too big for anyone to care.  On a quick search the figure of 4TB 
was mentioned on LKML.

There was a 2GB limit _per swap space_ but even that has been gone for 
quite some time, and in any case it was easy to work around that by 
using multiple swap spaces.

I regularly build systems with a single swap space larger than 2GB and 
they work just fine.

Cheers,

Rob
