I had this sporadic traceback in a project:

  File "test.py", line 62, in <module>
    result = do_lqs(client, str(dnvn))
  File "test.py", line 25, in do_lqs
    qualif_service_id = client.create('ti.qualif.service', {})

It seems that the EINTR should be caught by the standard library in all cases: http://bugs.python.org/issue1628205

But it's not the case for the "socket.create_connection" method (verified in 3.3 and 2.7 source code).
