Sorry, rb_thread_polling() returns immediately if only one thread runs.
rb_thread_wait_for() should be used instead.

  while ((result = WaitForSingleObject(handle, 0)) == WAIT_TIMEOUT) {
    struct timeval tv;
    tv.sec = 0;
    tv.usec = 100000;
    rb_thread_wait_for(rv); /* sleep 0.1 second */
  }
