I was thinking about automatic swap set-up. If you do that
with a non-random key, you have to store it somewhere and that 
will be a problem. This assumes that encrypted swap is
completely independent from the presence (or absence) of any 
other encryption.

Or are you asking why unencrypted swap is insecure?
