Perhaps not - it depends on the performance criticality of your application. If 
you don't supply a dictionary, the impact is minimal. If you need better 
performance you can roll your own LogRecord subclass and do everything inline, 
as Skip has mentioned. And if one wants this functionality, and don't check on 
every call, when would be a good time to check?
