Ooops! It looks like Pyborg has crashed. Would you like to save its dictionary? (y/n) Writing dictionary...

This seems to be a race from sending a reply (via a thread in process_msg) and processing the QUIT.

The exception is when socket == None which without threads wouldn't be possible since it read from the socket fine (and didn't hit an EOF to trigger setting socket = None) to process the monoffline reply.

So it must have sent a reply right after reading the monoffline from the socket and before it sent NICK back to the server.
