I think there's a confusion of terminology here. If a sample played
back at a higher frequency is shorter, then I was calling it
variable-rate playback (even if the clock frequency is fixed). I was
using the term "pitch-shifting" to refer to transformation of the
pitch without affecting the (apparent) playback rate.

I suppose we're getting to the stage where the two techniques are
starting to overlap...
