	Well, I'm wondering if anyone has an interval that long where they  
don't mean ``forever.''  It might be enough to say 0 == no time-based  
invalidation.

	As a cache, it should be considered possible that an entry may  
disappear at any time and you'll have to regenerate it.  If you did  
have something you wanted to expire at an exact moment in the future,  
you could cache it with max(timeToExpirationDate, MAX_EXP_INTERVAL)
