With zodb-3.6.0 I occasionally see the error:

ERROR:ZEO.zrpc.Connection(C):(localhost:12345)
Asynchronous call raised exception: <ManagedClientConnection
('127.0.0.1', 12345)>
Traceback (most recent call last):
File "/usr/lib/python2.4/site-packages/ZEO/zrpc/connection.py", line
421, in handle_request

                                ret = meth(*args)

                                                   File

invalidateTransaction

self._cache.setLastTid(tid)

                        AttributeError: 'NoneType' object has no
attribute 'setLastTid'

I'm just connecting to the zeo server and then starting the asyncore
loop thread. Maybe there is some race condition there?
