The documentation doesn't mention that the function always returns 0 if called from a thread which is not the main thread, or an interpreter which is not the main interpreter. Only the main thread of the main interpreter can return 1.

I thought about that, but I didn't think it was particularly important; it's technically an implementation detail, it's not too noticeable in practice, and most people should use PyErr_CheckSignals anyway. Feel free to submit a follow-up PR if you feel strongly about documenting that.
