No please. We need to set the foreground process.

As discussed in #369 (comment), bwrap and its child process have already been foreground processes by default, we shouldn't need to do anything further.

Nope. You can see this #735 works.

Unfortunately it doesn't. I've replied there.

FWIW I can confirm this works for me for interactive workloads, and is much simpler than trying to forward signals the right place.

Code-wise looks good to me but I'm not a contributor so take with a grain of salt, sorry for the "+1" style comment.

I also tried #586 (rebasing around the conflict manually) and it works as well but I feel that simpler is better here. I didn't try the recent LLM-assisted PR...
