After further investigation it appears that there is a simpler approach.  Simply defining

(define (abort-io port)
  (input-port-timeout-set! port -inf.0))

is sufficient.  There is no need for the thread-interrupt! call because the functions input/output-port-timeout-set! contain the logic to force the waiting thread to wakeup.
