Grant-

diskin appears to change the rules depending on kpitch. If kpitch is static
such as:
    kpitch init 1 ;play at normal speed and pitch
         or
    kpitch init 2 ;play at twice as fast, octave higher
then, iwraparound works as expected.

But if kpitch is a moving value, such as:
    kpitch line 1, p3, 2
then iwraparound seems to have no effect. The soundfile is looped until the
end of the note.

I don't know if this is broken, or if it must work this way for some reason
- the manual isn't too clear on this point. Anyway, you might be better off
using GEN01 and a table or oscil opcode, especially if you are accessing the
sound several times in the score.  A .2 sec soundfile isn't that large and
diskin is intended for large soundfiles.

Hope this helps.
