Script to run startlette & uvicorn in a way that forcefully exits/kills all pending background tasks automatically. A must have for development!

main.py

"""
Tired of seeing this annoying message - "Waiting for background tasks to complete."?
This hack can take care of that for you!

Usage -
    $ python main.py

Bonus - easy to attach a debugger now
    $ python -m pdb main.py
