logilab-database #208555 have a sequence-like numrange object allowing to reserve whole number ranges [validation pending]
The current sequence is used to generate eids in cubicweb.
However, whenever one wants to reserve whole eid ranges (of, say, size N), one must perform N increment_sequence calls.
We will now be able to reserve number ranges in O(1) steps.
