Is there a way to kill a Julia runtime?

I want to use Python multiprocessing to call a Julia function in parallel, which works fine, as long as I don't import `juliacall` outside Python's `Worker` context (either in the main script directly or in any function that eventually get called from the main script).

I don't know what's causing it, but I feel like if I can kill the current Julia runtime after `Worker` has done its job, then it should be fine to call `juliacall` in the main script.
