Ok, so are there other types of sockets that aren't "blocking" ?
Yes, sockets can be either blocking or non-blocking. An I/O operation on a 'blocking' socket will not return until the operation is complete. If you try to read more bytes than are currently available, the call will block, possibly forever. Operations on non-blocking sockets return "immediately", but are not guaranteed to have completed. For example, a write() of 1024 bytes may only succeed in writing 10 bytes. It's up to your application to keep track of this state. Google around for socket programming tutorials for complete information.
WRT Python, you'll quickly find that asynchronous programming becomes tedious without a framework. As JP suggested, check out http://www.twistedmatrix.com. Twisted does a good job of abstracting away a lot of the low-level details and allows you to focus on implementing the functionality of your program.
Good luck,
