It basically determines the time after a client that was querying very
fast but then stopped is allowed to receive responses again.

When a client repeats a query, its counter is decremented until it reaches
the minimum `-1 * window * responses-per-second`. Its counter is
incremented by `responses-per-second` each second, so after the client
stops querying it will be `window` seconds before the counter becomes
positive which means the client is allowed to receive responses again.
