As someone else mentioned, most of the delay is because of waiting for the
harddrive to wake up. By the time you skip two tracks in a row, the
harddrive will hopefully have had enough time to be active again. Then
rockbox would presumably discard whatever was left of the prebuffer, and
then fill both buffers back up with new information.

Also, if the prebuffer is kept as short as possible, say 4 or 5 seconds,
then perhaps this won't be too much of an issue. People usually have to hear
at least a few seconds before deciding to keep or skip a track.

Even in times that the tracks were switched quickly and the prebuffer had to
be partially discarded, it could still possibly be faster than the current
way, because of the harddrive's head start in spinning up.
