Why you shouldn't use SQLAlchemy 1.3 with FastAPI
"""
This code demonstrates how FastAPI server freezes with SQLAlchemy under concurrency,
if you're mixing blocking operations with async calls inproperly.
(pip install sqlalchemy httpx fastapi uvicorn)
You will see 15 (not 20!) "Handling xxx", then the server freezes for minutes,
refusing to serve any request.
This is caused by "resource starvation" - the default SQLAlchemy connection pool size
