I upgraded my ZEO server to 3.9.6 in preperation of some Zope 2.12 tests
and found several disconnects in the log. They all looks like this:

2010-12-03T10:47:24 ERROR ZEO.zrpc (2515) can't decode message:

And no, ZODB 3.9 does not work with Python 2.4. This is an not announced
API breakage between the server and client.
