The log message for conflict errors is far less instructive than
it could be (almost without any effort).
It should indicate whether it is a ReadConflictError or
a (Write)ConflictError.
It should tell which object caused the conflict.
The attached patch to "Zope/App/startup.py" provides this
additional information.
Please file a feature request to "<http://collector.zope.org/Zope>".
