Research direction

No files, tests, or entry points are named. Start by locating the subinterpreter execution path and the signal-handling path, then compare how the main interpreter handles interrupts. Done means interrupts raised during subinterpreter execution are propagated to the C++ side.

Description

bug

Subinterpreters don't handle interrupts when they are in execution (see cpython issue 113130). The main interpreter is the only one which performs signal handling.
