[New-bugs-announce] [issue7795] BaseManager of multiprocessing module throws an exception if socket.setdefaulttimeout is set

[Jonas Weismüller]

New submission from Jonas Weismüller <jonas.weismueller at gmail.com>:

If socket.setdefaulttimeout is set to any value (except None), the BaseManager raises an exception and the execution of the remote object fails:
Traceback (most recent call last):
  File "client.py", line 16, in <module>
    m = Manager()
  File "client.py", line 12, in __init__
    self.connect()
  File "/usr/lib/python2.6/multiprocessing/managers.py", line 474, in connect
    conn = Client(self._address, authkey=self._authkey)
  File "/usr/lib/python2.6/multiprocessing/connection.py", line 140, in Client
    answer_challenge(c, authkey)
  File "/usr/lib/python2.6/multiprocessing/connection.py", line 371, in answer_challenge
    message = connection.recv_bytes(256)         # reject large message

See the attached client.py (uploading soon) and server.py file to reproduce the error.
