Given the distributed nature of Tahoe, there isn't a good way to figure out
when shares are no longer needed.  The solution is to periodically tell all
of the storage nodes "Yep, I still need that".  Without such a notification,
the storage node eventually removes the share.  That's expiration.

I suspect the tahoe backup command renews leases for you, so maybe this
isn't as big a deal as I'm making it out to be.  My backup server (when it
works) will renew leases automatically.
