This is right.

It is fine with me to raise AttributeError(name).
Note that when raising AttributeError('socket'), the user gets
notified of the exceptions on both 'socket' and 'name'.
For example with the patch applied:
$ python3
Python 3.2 (r32:88445, Jun 18 2011, 20:30:18)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import asyncore
>>> a = asyncore.dispatcher()
>>> del a.socket
>>> a.foo
Traceback (most recent call last):
File "asyncore.py", line 415, in __getattr__
retattr = getattr(self.socket, attr)
File "asyncore.py", line 413, in __getattr__
% self.__class__.__name__)
AttributeError: dispatcher instance has no attribute 'socket'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "asyncore.py", line 418, in __getattr__
%(self.__class__.__name__, attr))
AttributeError: dispatcher instance has no attribute 'foo'
