 `EnforceDistinctSubnets`.

 I haven't looked at the other changes, but this one sounds plausible to
 me. I imagine we're going to have a much more non-uniform load on bridges
 given out with this distributor, since some /16's have lots of users in
 them and some /16's have zero users in them. Or actually, maybe this isn't
 true, since we're breaking the bridges into a reasonable small number of
 buckets and mapping each /16 onto a bucket, so there will still be many
 many /16's that map to each bucket, thus making the distribution more
 uniform? Or am I misunderstanding where the design has gone?
