Add a `zombicide` script to macOS workers. #19

Closed SimonSapin closed 4 years ago

SimonSapin commented 4 years ago

It looks for processes whose executable was under /Users/worker/tasks/ but has been removed, and optionally kills them.

CC servo/servo#24735

Example usage:

Next we could add a cron job to run this regularly, but I’m not sure yet we should have this kind of thing run unattended.
