Actually, you are also experiencing issues with the classloader (for instance,
the cross polination of log events.  I will post this issue on the Avalon-dev
list.  Hopefully, with Giacomo's LogKitManager this can be dealt with.  Cocoon
does not do anything special with the LogKit Hierarchy to force different
roots or default loggers for different contexts.  This could also be taken
care of with a classloader solution I proposed a while ago.

TO THE AVALON TEAM:

LogKit is cross-polinating log events to log targets that belong in another
web context.  The change in configuration is that LogKit is now loaded in a
base ClassLoader, and not in the unique ClassLoaders that are used for web
apps.  The result is that the Heirarchy object is shared between all contexts.
We need a way to enforce all Contexts to be separate.
