You need to override the handle_error() method of the asyncore base class.
The base class method sends a compact stack trace to the log_info() method,
which just does a print.  Logging in general might be useful to you, so you
might also want to override the log_info() method.

If you want the asyncore.loop to break on an exception (don't do this on
server side!), just do something like this:

def handle_error (self):
    raise
