* fhandler.h (fhandler_base::has_ongoing_io): Declare new function.
* fhandler.cc (fhandler_base::has_ongoing_io): Define new function.
(fhandler_base::read_overlapped): Use has_ongoing_io to avoid writing when
handle has not completed last I/O.
(fhandler_base::write_overlapped): Ditto.
* select.cc (peek_pipe): Be more careful about accessing hEvent field from
get_overlapped().
