I wanted to get this patch into RT so it's not just a message in my inbox.

I'd like to consider it for 5.21.

Hello everyone,

I've attached a patch that allows users to (more easily) debug forking
processes when using tmux. The implementation simply creates a split
window and associates it with the child process.

Thanks,
Rob Hoelz
