     I think you snipped just a bit too much above.  You wrote that the
relay needs to recognize when its descriptor is about to expire.  I asked
which descriptor [is about to expire]?  So your reply above is nonsensical.
(Surely, a brand-new descriptor is not just about to expire?)  The new
descriptor is generated to replace some earlier descriptor, namely, either
the descriptor that was already in effect at the time of the failed update
or else the descriptor that failed the update.  So which one's timer is used
to ascertain that a descriptor is about to expire?  I argue that, in the
event of an update failure, the expiration time of the descriptor already
on file at the authorities should be used to determine when a new descriptor
should be sent to the authorities, not the expiration time that would have
applied to the failed descriptor had it succeeded.

     Okay.  I hope it works.
