Are you aware that my ParameterizedMessage supports both #70 and lazy  
initialization?
This is possible since the placeholders are only counted during  
creation. The actual formatting/placeholder replacement is only  
performed when the formatted message is requested. The formatted  
message is kept so it won't be regenerated in case of further calls.
It could also be enhanced to perform the toString of the arguments at  
a later time. The Message interface could be extended by an  
prepareForDeferredProcessing() method for that purpose.

I agree with Ralph that this would be a good time to extend the Logger  
interface with Message-aware methods since 1.6 will be incompatible  
anyway.

This wouldn't mean that varargs need to be added at this point.
