New submission from Andrew McNabb <amcnabb at mcnabbs.org>:

In PyPy 1.8.0, I came across a race condition when calling getattr. This race 
condition appears to only occur pypy; I cannot reproduce it in cPython 2.7. 
Specifically, in multithreaded code, I occasionally encounter the following 

2012-03-12 13:56:37,004: ERROR: Traceback: Traceback (most recent call last):    
  File "/home/amcnabb/python/mrs/http.py", line 157, in _marshaled_dispatch        
    response = dispatch_method(method, params)                                     
  File "/home/amcnabb/python/mrs/http.py", line 128, in _dispatch                  
    return self.server._dispatch(method, params, host)                             
  File "/home/amcnabb/python/mrs/http.py", line 177, in _dispatch                  
    func = getattr(self.instance, 'xmlrpc_' + method)                              
LookupError: unknown encoding: ascii

I can work around this by adding the following lines at the module level:

import codecs
