Short usage periods of subkeys and key roll over is actually a Good
Thing to limit the damage in case of key compromise or RIPing.  The
problem is that most keyservers are not able to cope with multiple
subkeys and that you need to have backup copies of the old secret keys
to be able to decrypt old mails.

Hmmm, PGP can't cope with signing subkeys :-(
