Pyodide SharedArrayBuffer interrupt mechanism does not interrupt C-level Python builtins
When using Pyodide's SharedArrayBuffer-based interrupt mechanism to implement cancellation, setting the interrupt flag via buffer[0] = 2 will reliably trigger KeyboardInterrupt in pure Python code (bytecode execution). However, this mechanism cannot interrupt tight loops written in C-level Python…

Pyodide SharedArrayBuffer interrupt mechanism cannot interrupt C-level Python builtins like sum()
When using Pyodide's SharedArrayBuffer-based interrupt mechanism to implement cancellation, setting the interrupt flag via buffer[0] = 2 will reliably trigger KeyboardInterrupt in pure Python code (bytecode execution). However, this mechanism cannot interrupt tight loops written in C-level Python…
