IOhanness: I could not reproduce that speedlim bug... do you have a demo patch, perhaps? There is one ambiguity, might this be related? -- if the time interval changes after clock has been set, it is not clear if the clock should be rescheduled or not. Cyclone's speedlim does no rescheduling, just as c74's (at least it did not last time I checked, which was over 2 years ago).
i asked thomas whether he could try it again: and lo and behold, he wasn't able to reproduce the bug either.
so i think you can file that one under "fixed" ;-)
sorry for the inconvenience
