Post command hook is called much more frequently. > So I think the sleep in the filter handling should be removed. (This is > in addition to disabling the filter upon some threshold or other.) I see no reason. If the mechanism of disabling such a filter will work reasonably well, the sleep will annoy a few times, and then go away. I understand that it pissed you off, but the situation where it happened will be resolved by the automatic disabling, so your past annoyance doesn't need to affect anything else. IOW, I think you are over-reacting here.
