In the event a certificate is compromised Certificate Revokation Lists 
(CRL) lifetimes, not the certificate's lifetime, determines how big the
exposure window for a compromised certificate.

If you re-issue (and check) CRL's daily for 10 year certificates, your 
exposure is a day, not 10 years.

Stupid question - what percent of deployed software actually does CRLs
correctly?
