Object lifetime beyond pybind11's module lifetime.

[JulianSchutsch]

Env: Python 3.12.7, Pybind11: 2.13.5-1, Linux: Xubuntu 24.10.

When catching unloading of the library using atexit, following pattern shows in the logs:

• Normal operation, all fine, some objects created held by std::shared_ptr
• Unload message of pybind11 module X
• Destructors invoked for objects which depend on X
• -> Segfaults in some cases

This can be avoided by using manual del on objects in question, but, is there a more elegant way? Delaying unload of the pybind11 module maybe?

Thanks in advance.
