MQTT Disconnect socket write then close

[AngeloFatica]

When there are network issues and I want to disconnect from mqtt client, the socket writes are blocking and cannot be changed (I havent been successful) so it will just hang on the self.sock.write(b"\xe0\0") line in the disconnect function of simple.py. Is this a necessary action, or can I not write that byte array and just close the socket so that I do not have to worry about hanging on the write indefinitely?
