Arg. After my last rambling message, I realized I might have missed the 
mark of what you were asking.

Did you want:

   (A) The have existing references to Logger refresh themselves and 
start logging to the new file? or

   (B) To have existing references to Logger remain unchanged and have 
new loggers start logging to the new file?

(A) is not so simple to do (as I mentioned in my last post). (B), 
however, would be much more straightforward.
