Minor performance hit

I noticed on procexp that svp takes about 8 million cycles/s when being idle. That's not enormous for this cpu but I suppose it could be limited to the cycles most services get, e.g. up to 8k. I guess it looks for avisynth raw input every few milliseconds or something. I guess if it were looking for it every 0.2seconds or so it would limit the cycles to almost nothing and still not be noticed by the user.
