Indeed, I forgot that.  The following output was generated with
DrRacket 5.1.1 in Window 7 while moving the slider from 0 to 4. The
extra callback calls are generated when the mouse button is released.

slider at -469734252: 0
slider at -469729961: 1
slider at -469729750: 2
slider at -469729177: 3
slider at -469728498: 4
slider at -469727374: 4
slider at -469727374: 4

Just clicking the slider (without moving it) also causes two unnecessary
callback calls.

Thanks,
António Leitão.
