Summary

# sleep.py
import time

time.sleep(100000)

uv run sleep.py

Then I manually kill uv process in Task manager. I can still see the Python process.

On MacOS/Linux, if I kill it with kill pid (which sends SIGTERM), the Python process will exit. Though I also notice that if I kill with SIGKILL instead kill -9 pid, the Python process does not stop.

In a larger context, in my application, I'm trying to spawn uv as a subprocess to launch Python apps. And I want to be able to kill the uv subprocess and its python process. Having troubles to do it on Windows right now.
