It all starts to make sense again with servers that combine several
services into one application, especially if some involve persistent
You don't want to bounce offline all users currently using the IMAP and
IRC servers every time you make a small change to a web page.

Or, if you have a large application which takes serious time to startup,
the waiting gets you mad in no time.

The rebuild() solution mentioned by Christopher Armstrong mostly takes
care of that.
On-the-fly reloading can be hell, but the ubiquitous "server reboot" is
what I *really* disgusted in most J2EE implementations. I really hope
twisted is not going to enforce this.
