same key stored twice

[Kevin Lewandowski]

I've found the problem. The Python client uses the "hash" function to
determine the server for lookup and storage. My existing servers were
running Python 2.3.5 but my new ones run Python 2.3.4. And it looks
like those versions return a different hash value for the same key.
bad.

Thanks all for your suggestions.
