+ * Test to validate that monitoring a PTY device, FIFO, pipe, or socket pair in
+ * a dispatch source, kqueue, poll, or select delivers read events within and
+ * between processes as expected.
+ *
+ * This test catches issues with watching special devices in kqueue(),
+ * which has tricky special cases for character devices like PTYs.
+ *
+ * It also exercises the path to wake up a dispatch worker thread from the
+ * special device kqueue event, which is also a special case in kqueue().
+ *
+ * See rdar://problem/26240299&26220074&26226862&28625427 for examples and
+ * history.
