But we don't do this with errors that happen in other circumstances -- just the filter errors, I think? (And some errors are so annoying to deal with that we disabled them immediately if they happen. For instance, if a function in post-command-hook happens, we just remove the function immediately.) 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.) -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
