What is a safe way to stop a running thread?
Put the thread in its own process. When you want it to stop, kill the process.
That is the only safe way to kill a thread. Aborting a thread can severely destabilize a process and lose user data. There's no way to avoid the "lose user data" scenario if you really, truly need to be able to kill a thread that could be doing anything. The only way to avoid destabilizing the process that is calling for the abort is to make them different processes entirely.
