You need to wrap the code for each I/O call in something like this:

try:
    # I/O call
except IOError:
    # handle exception

If the exceptions are going directly to the main thread, you've probably
got a platform problem with signals.  I'm not familiar with
SocketServer, so I don't know how to translate this to your specific
situation.
