[Web-SIG] serving (potentially large) files through wsgi?

I'm not sure.  What I did with paster serve was expedience, I'm not sure 
it's right.  I guess paster serve technically also sets up the process, 
not just the server (which might justify things like --reload for the 
reloader, which is really process-wide).

It's just using logging.fileConfig, though apparently we backported 
Python 2.5's logging.config module.

Stuff ends up in paster serve usually because I don't know where else to 
put them.  Of course applications could take options to setup the 
configuration on their own (e.g., paste.translogger sets up logging, 
since without logging it's useless).  This lets applications be a little 
more lazy, which is kind of what the logging module encourages (but only 
kind of).
