unless you are experiencing timeout and you know it's due to slow data
loading.
Sometimes full `shared_memory` will cause all workers to hang and
causes timeout. In these

Review comment:
Here's what I set for `try_nopython`:
- `True` to explicitly check for failure cases, e.g. raise warnings if pure
c++ loading is not available.
- `False`, do not engage c++, always use python
- `None`, check for c++ and enable silently, if not available, fall back to
python silently. This is designed for user who DON'T care
