Depending on version that's not a bug either.  A lease that is 'offered'
is not allocated.  We check billing when we offer a lease, but we unbill
before the offer is sent.  This was a bug fixed in 3.0.x maint, I can't
remember which one, but an older version would bill offered leases.

This was a problem: if you bill a lease, set its expiration forward 2
minutes, and put it back on the free list, it will never 'expire' and
be unbilled unless it is allocated by another client at which time the
old billing is noticed (or the daemon is restarted).

When the client REQUEST's a lease, we'll bill, and it would be odd for
the client to have more than 2 in that case.

Really, that's the point at which the resource is allocated.

Odd.
