Buckets refer to data, and the data can come from any source it's wants
to, including pools.  The question here is where do the buckets themselves
get allocated from.  Buckets can not be allocated out of a pool, and still
survive for the correct lifetime, because we don't know what the lifetime
will be when the bucket is created.

I guess I don't see which buckets can safely be allocated from
pools.  Perhaps if you could explain that to me, we could figure this out
