User:StasFomin/Bugs/SubscriptionManager/Timeout

Sometimes I see infinite hanging (>10 hours) of subscription-manager on connecting to Candlepin (on every operation, like «subscription-manager identity»).

I debug SM, and see, that in /usr/lib64/python2.6/site-packages/M2Crypto/SSL/Connection.py self._timeout set to -1, because self.socket.gettimeout() is None:

        self._timeout = self.socket.gettimeout()
        if self._timeout is None:
            self._timeout = -1.0   

On /usr/lib64/python2.6/site-packages/rhsm/connection.py I see attempt to set global timeout, but (why?) only for python <= 2.4

    if sys.version_info[0] == 2 and sys.version_info[1] < 4:
        socket.setdefaulttimeout(global_socket_timeout)
        timeout_altered = True
        return

Why global timeout is not set? Can it be set without patching subscription-manager?
