This has been discussed on the list several times before.
No there is not an intermediate state when allocating IP addresses because if
you miss an accounting start record, you will reallocate an in-use address and
then everything will break.
Some of our customers have made these modifications, but if you do decide to do
this be aware of the consequences and be very careful.
Note that there are address reclaim parameters that you can use instead.
Have a look at sections 6.43.3 (DefaultLeasePeriod) and 6.43.4
(LeaseReclaimInterval) in the Radiator 2.17.1 reference manual.
