When the passphrase gets compromised it'll be of no relevance what
somebody will find inside the unencrypted swap. All swap content 
is derived from data of the system itself, which then also will be
compromised. At least if a global passphrase is used.

If every partition on a system has its own and unique passphrase, nobody
would attack swapspace in the first place. There's more to get
attacking the users /home or the root-partition.
