The reality is that returned address space has been going back to IANA and will continue to do under current practices; see <http://blog.icann.org/2008/02/recovering-ipv4-address-space/

I think that this is a fairly important bit to comprehend the full picture.
Well, this is slightly disingenuous, as IANA currently only accepts returned /8s. Part of the global policy proposal was to encourage IANA to accept smaller blocks for distribution that would otherwise be stuck with the RIR in which they were returned. Also of course, the argument that this policy does not comply with the "at need" practice currently followed by RIRs is a little shaky too. This policy only kicks in once the IANA pool is completely exhausted. All RIRs will be able to make justification for the tiny remaining dribbles of IPv4 space that this policy will generate. As noted several times today, this policy is not about usefully extending the life of IPv4. It is about showing that RIRs are able to act in a magnanimous and equitable fashion with the last remaining dregs of an irreplaceable resource. Nigel
