Interesting technology. I'm playing around with your sample, but the project
is in bad need of some documentation. At least a man page for the pannus
A couple of questions:
How do you debug your application after it has been patched? It's pretty
easy to send a bogus patch (did it a couple of times so far while
experimenting with the technology), but when the process segfaults...
Do you think the time delay in applying the patch will need to always be
as long as it is now? Looks like we interrupt the process for 5sec now.
Wouldn't that cause you to loose most of your sessions and therefore loose
the benefit of not just stopping/starting to a new version of you app.
