Improve performance significantly. We store if (and if: why) a certain domain was blocked for any requesting client and can immediately reply similarly if the same client requests the same domain again. This reduces the O(N^3) problem (number of queries * number of domains * number of clients) to a O(N^2) problem (domains * clients). Note that this state of the code still lacks a possibility to reset when entries in the database have changed. For this, we still have to send either SIGHUP (drawback: clears the cache) or define a new signal for it.
