Description:
 def _raise_timeout(self, err, url, timeout_value):
 """Is the error actually a timeout? Will raise a ReadTimeout or pass"""


        if isinstance(err, SocketTimeout):
            raise ReadTimeoutError(self, url, "Read timed out. (read timeout=%s)" % timeout_value)

        # See the above comment about EAGAIN in Python 3. In Python 2 we have
        # to specifically catch it and throw the timeout error
        if hasattr(err, 'errno') and err.errno in _blocking_errnos:
            raise ReadTimeoutError(self, url, "Read timed out. (read timeout=%s)" % timeout_value)

        # Catch possible read timeouts thrown as SSL errors. If not the
        # case, rethrow the original. We need to do this because of:
        # http://bugs.python.org/issue10272
        if 'timed out' in str(err) or 'did not complete (read)' in str(err):  # Python < 2.7.4
