That problem is easily avoided by wrapping the whole script in a function and then calling it on the last line.

It looks like Patchwork's script doesn't quite do that, but it does put _most_ of its functionality into functions, and AFAICT there is no particular place in the script where a connection loss could lead to anything bad happening. Admittedly this appears to be a lucky accident rather than following best practice.
