'Resource temporarily unavailable' errors in server applications on HP-UX

[rptownsend]

Since installing Python 2.3 on HP-UX11i, I keep 
getting 'Resource temporarily unavailable' errors in server 
applications.

E.g. using ../doc/examples/simpleserv.py 
& ../doc/examples/simpleclient.py:

"richardt" capulet:doc/examples > python simpleserv.py 
Traceback (most recent call last):
  File "/opt/python/lib/python2.3/site-

  File "/opt/python/lib/python2.3/site-

    return context.call({ILogContext: newCtx}, func, *args,

accept
    sock, addr = self._sock.accept()
socket.error: (11, 'Resource temporarily unavailable')


"richardt" capulet:doc/examples > python simpleclient.py
Server said: hello, world!
connection lost
Connection lost - goodbye!


The transaction appears to work, but the log file is 
filling up with these
errors. This happens with Twisted 1.0.6 and 1.0.7.

It doesn't happen when using Python 2.2

Fixed in CVS.
