What happens?
I ran cext-review-toolkit on duckdb-python and got a report with some issues:
The primary risks are: (1) Python API calls without GIL in the parallel numpy scan path (data corruption/crash), (2) PyTuple_Pack reference leak in map.cpp (~11 KB/call), (3) unchecked PyNumber_Rshift NULL in 128-bit integer conversion (segfault), (4) PyErr_PrintEx clobbering exceptions in map and filesystem, and (5) UDF exception handling that optionally swallows MemoryError/KeyboardInterrupt.
The full report is available at https://gist.github.com/devdanzin/5c7600153c8e76afee3ef1a2d516ad70
