But then you have to re-setup all the affected components.

And some components (e.g. Class::DBI stuff) rely on classdata so that may not 
work properly a second time. And some components may depend on other 
components, and you don't have any way to tell.

It becomes a lot easier at that point just to reload the app. *Although* you 
could try re-running ->setup entirely and see what happens. Not sure how well 
it would work, but it's probably worth playing with.

I think it's probably more like a Plugin::RestartApp - that way you can have 
it happen off of HUPs and similar as well.
