scrubbing with the keyboard left/right keys held down is slow

Description
Support for scrubbing the timeline with the left/right arrow keys was recently added, but it seems to me like there's something fishy with the performance if I hold down the left/right keys: I can scrub the clips very fast with the mouse, but with the keyboard, it doesn't keep up with the previewer (which refreshes every few seconds, and sometimes crashes).
My unscientific guess is that it tries to play much more than the actual amount of frames in the clip.
