Since my application is also web server related, I was curious enough to 
look at this blog posting to see if it would be a good starter example 
that is missing from the manual.  I don't think it is, as it is somewhat 
complex, although it is multi-module, and even multi-thread, so it might 
make a good example for other parts of the documentation (but maybe they 
already have good examples; I've only looked at the first 8%).

In trying to understand it, I couldn't figure out why the WebApp class 
needs to keep track of the threads that are running the that web app.  
Why isn't it good enough for the thread to know the name of the app?  
The filter copies the appName from the thread to the record; the 
InjectingFilter.filter not replace

         record.appName  =  tlocal.appName
         tname  =  threading.currentThread().getName()
         return  tname  in  self.app.threads

by

	record.appName = tlocal.appName
	return appName == self.app.name

and get the same effect, without needing to mainting the self.threads "database"?

Or what am I missing?
