As per http://docs.python.org/2/howto/sockets.html#using-a-socket it's possible that a socket recv() call returns 0 bytes if the remote closes the connection. In that case, recv() does not obey settimeout(): it just doesn't block and returns zero bytes immediately, which in this case results in an infinite loop if the transmission was incomplete.
PyBitmessage
Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.
