Remedy socket 35 errors on all Python builds

[ben@…]

OSX's poll is broken. Apple knows this, and removes the HAVE_POLL option as can be seen in the first line of the pyconfig patch here:

​http://www.opensource.apple.com/darwinsource/10.5.6/python-30.1.2/fix/pyconfig.ed

This patch should be applied to all Python builds that MacPorts supports, as it fixes a nasty bug that is being mis-reported all over the place on OSX. Here's one such example of a traceback caused by it:

File "../uploader.py", line 94, in <module>
   resp, data = http.request(post_uri, 'POST', body=content, headers=headers)
 File "build/bdist.macosx-10.5-i386/egg/httplib2/__init__.py", line 1050, in request
 File "build/bdist.macosx-10.5-i386/egg/httplib2/__init__.py", line 854, in _request
 File "build/bdist.macosx-10.5-i386/egg/httplib2/__init__.py", line 823, in _conn_request
 File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/httplib.py", line 874, in request
   self._send_request(method, url, body, headers)
 File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/httplib.py", line 914, in _send_request
   self.send(body)
 File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/httplib.py", line 719, in send
   self.sock.sendall(str)
 File "<string>", line 1, in sendall
socket.error: [Errno 35] Resource temporarily unavailable

And another report caused by the same problem: ​http://www.cherrypy.org/ticket/598

Applying the same regexp that Apple does, fixes the problem in my tests.

Credit for finding this bug and its solution should be attributed to Phil Jenvey, I merely bugged him until he found the problem for me. :)

This should be clarified, its not 'broken' per se, but merely returns an EAGAIN error rather frequently causing the socket issue, which very very rarely occurs on other platforms. This causes a decent amount of Python code, including httplib2, to throw up the socket 35 error.

Out of curiosity, could depending on the port ​poll-emulator and using its poll implementation instead be another way of getting around this issue?
