What swamp?  There is active space and dormant space. Registries are 
generally provisioning out of active space (by definition) and the
dormant space is delegated space that is not being provisioned from
-at this time-.  

Current dormant space does have some interstital gaps of undelegated space.
This is true -all- the way down the delegation heirarchy. (retorical 
question; have you used 100% of your cidr block?) There are efforts to 
develop a process to identify and reclaim prefixes that are inactive
and are expected to remain so regardless of the active or dormant state
of the block.
