   I don't think I asked the original question very clearly. What I
   should of asked is "has anyone using the new 2.3 logging package
   found blocking behaviour?".  Yes would mean I'd have to handle the
   logging with a different package.

   As it turns out, the new logging package can listen on a socket for
   configuration instructions and it uses threading locks to ensure
   thread-safety of its shared data structures, so I'm proceeding with
   caution ;-)
