 Fixed several critical ZEO bugs.
 
+- If several client transactions were blocked waiting for the storage
+  and one of the blocked clients disconnected, the server would
+  attempt to restart one of the other waiting clients.  Since the
+  disconnected client did not have the storage lock, this could lead
+  to deadlock.  It could also cause the assertion "self._client is
+  None" to fail.
+
 - If a storage server fails or times out between the vote and the
   finish, the ZEO cache could get populated with objects that didn't
   make it to the storage server.
