Hi Jon, thank you for the code.  I noticed that comment from Mike but
he referenced a related security issue which scared me off.  Do you
know what he was refering too?

If I do implement it that way, to make sure my understanding is
correct, I should synchronize the expiration times in Vend::Expire,
SessionExpire, and in my find command which deletes old session
files/dirs?
