Hi everyone! I found a few threads re. PyO3 memory use, the GIL, releasing the GIL to free memory, etc. (PyO3/pyo3#311, https://github.com/Renmusxd/pyo3_memory, PyO3/pyo3#319). In my package https://github.com/BenSchZA/radCAD I'm creating large lists of dictionaries, calling Python functions, and passing the list to those functions. In Python, that process uses maybe 500mb of memory, in PyO3, it quickly ramps up to 5GB+. The library is less than 300 loc, so maybe someone would be able to suggest a solution - because I'm relying on creating and using large PyLists maybe there isn't a way to free the memory easily?
