I have tested the latest CVS version, and found
a new problem.
With new CVS version, slave side can not detect
closure of master.
Please use following Test Case 3. Test Case 3 is
not terminated by itself with latest CVS.
It seems that the program is stopping at
cygwait(input_available_event, time_to_wait)
in fhandler_pty_slave::read().
I guess input_available_event should be set when
the last valid master fd is closed.
