That won't help.  The messages are coming from the controller.

The controller needs to be more careful about how it manages it's log
file.  It needs to keep track of the handler used and, when the
transacript file is reopened, it needs to remove the old handler it
was using and create a new one.
This is probably complicated by ZConfig which is managing the logging
configuration.  This is easy to deal with if you're willing to rely on
the logging systems internal details. :)
