TokioBinProcess - stray processes are sometimes left around

[rukai]

I suspect the solution may look like registering a sigint handler so that we ensure the child process is killed before terminating.

Note that we are already making use of this: https://docs.rs/tokio/latest/tokio/process/struct.Command.html#method.kill_on_drop

I actually havent seen this since I raised the issue, maybe it got accidentally fixed?
I'll leave it open for a while longer to see if it occurs again.

Yep, I havent seen this again since reporting, I think it was fixed.
