Looking at the code, the reason for this is that the timeout is handled by the NIC layer, and until you're connected (or bound), the socket doesn't know which NIC it's using. The timeout applies independently to each call to socket read/write operation. Use settimeout () to change the timeout of a socket to a floating point value representing the number of seconds to block before deciding the socket is not ready for the operation.
