How do I avoid blocking in the connect() method of a socket?
------------------------------------------------------------
The select module is commonly used to help with asynchronous I/O on sockets.
The :mod:`select` module is commonly used to help with asynchronous I/O on
sockets.
To prevent the TCP connect from blocking, you can set the socket to non-blocking
mode. Then when you do the ``connect()``, you will either connect immediately

-- ``0`` or ``errno.EISCONN`` indicate that you're connected -- or you can pass this
socket to select to check if it's writable.
