Long response time when calling unmatched requests

[kob-aha]

I'm using HTTPretty while setting 'allow_net_connect=true' when calling 'enable'. The problem is that when I call an unmatched URL it is forwarded to the real endpoint, however the response time is very long (about 1 sec).

I tried to debug it a little and it seems like HTTPretty uses the real socket and gets a response relatively fast, however it then keeps waiting on the socket for up to a second.

This is the relevant code from real_sendall in core.py:

should_continue = True
while should_continue:
    try:
        received = sock.recv(self._bufsize)
        self.fd.write(received)
        should_continue = bool(received.strip())

    except socket.error as e:
        if e.errno == EAGAIN:
            continue
        break

I see that it gets a response in a few ms and then simply gets stuck on sock.recv usually up to a second until it gets an empty data and exit.
I tested it with different URLs and got the same behavior.
