This does not seem to work. The attached Python 3.2 script
'asyncore_12498.py' goes into an infinite loop of calls to
handle_read/handle_close when handle_close is defined as above. In
this script the Writer sends a 4096 bytes message when connected, the
Reader reads only 64 bytes and closes the connection afterwards. Then
follows the sequence:
select() returns a read event handled by handle_read()
handle_read() calls recv()
socket.recv() returns 0 to indicate a closed connection
recv() calls handle_close
This sequence is repeated forever in asyncore.loop() since out_buffer
is never empty.
Note that after the first 'handle_close' has been printed, there are
no 'handle_write' printed, which indicates that the operating system
(here linux) states that the socket is not writable.
