      Modula-2 shared libraries.  *)

  EXPORT UNQUALIFIED sleepSpin, finishSpin, connectSpin ;

  (*
     finishSpin - sets boolean mustWait to FALSE.
  *)

  finishSpin
  PROCEDURE finishSpin ;

  (*
     sleepSpin - waits for the boolean variable mustWait to become FALSE.
                 It sleeps for a second between each test of the variable.

  PROCEDURE sleepSpin ;

  (*
     connectSpin - breakpoint placeholder.  Its only purpose is to allow users
                   to set a breakpoint.  This procedure is called once
                   sleepSpin is released from its spin (via a call from
                   finishSpin).
