If you never retire the old key it will always be used... I am not saying that 
this is a good idea, but it is possible.

If the user doesn't issue the ksk-retire command, either because they forget 
or because they don't want to, then they could just accumulate keys... again I 
am not saying that this is a good idea, just that it is possible.

Should we disable this option if it is not compatible with our rollover 
scheme?
