Hi Scott, I am not a developer on the Kea project, but I would assume that at the beginning of the reclamation cycle, a list of leases that can currently be reclaimed is obtained (all that currently match the correct state (expired) since "max-reclaim-leases" is 0). The "unlimited" time would be kea has as long as it likes to process that list (since "max-reclaim-time" is 0). Once that list is complete, now Kea is going to wait "reclaim-timer-wait-time" seconds before it pulls another list. At least that is what I assumed from reading between the lines in the documentation (and seems a sensible way to design the feature).
