It would be "un-Pythonic" to have real concurrency in Python.
You wouldn't be able to patch code running in one thread from
another thread. Some of the dynamic features of Python
would break. If you want fine-grained concurrency, you need
controlled isolation between concurrent tasks, so they interact
only at well-defined points. That's un-Pythonic.
