I love cargo watch, and use it all the time. I'm hitting an issue now though where I need to perform some cleanup/teardown prior to shutting down the watched process (I need some syscalls to complete in order to be able to re-run the process).

Unless I'm missing something, there's no ability to add a delay or customize the shutdown signal sent to the process, is that correct? I think in a perfect world, I'd be able to send a SIGINT, wait some number of seconds, and then follow it up with a SIGKILL if the process still hadn't exited.

Apologies if I'm missing some combination of features that make this already possible. I'm also open to contributing, if this is a feature that doesn't exist but you're interested in. Thanks!
