Comment(by bonefish):
Replying to [comment:9 mmlr]:
> I thought about using a list of sorted "free ranges" that can be
extended/joined on freeing an id and updated/removed on id allocation.
Could be made generic and used for area_id as well.
You might want to have a look at Bonwick's resource allocator (don't have
a link at hand, but shouldn't be too hard to find -- usually in
combination with the slab allocator), which was invented to do pretty much
exactly that. Though, a simple solution -- like an increment + lookup loop
until free spot found -- should work well enough (at least for alpha 2,
where I wouldn't want to introduce larger amounts of untested code
anymore), particularly in the cases where the domain (positive int32) is
several orders of magnitude greater than the total count limit.
