CPU load is still 2-5% at 10ms so it definately doesn't hog resources. What I did notice while writing this is that it steals focus from this window. (i.e. i'm typing and then can't type, click in the window, type and then lose focus again). Prolly not a problem in RR as RR tends to win the wrestle for window focus. Just something to keep in mind as you test it trying various things in RR to see if it would screw you up if you were trying to surf through RR.
