This is also what I think. Installing a signal handler is a fairly drastic action, and I don't think the code has been sufficiently reviewed yet.

How much more review should it receive?

I also share Alexander's concern that Python just shouldn't mess with signal handlers at all, ideally. So some trade-off has to be found to address that concern (e.g. by making the signal handlers only active for the executable interpreter, but not in the embedded case).

Well, Python already does (and also apparently messes with other things such as FPU state), so that's a separate issue altogether.

Regards

Antoine.
