Not really. I suppose I could but it doesn't get called for normal
arithmetic overflows so I would still need an FPE handler anyways.

I'm trying to figure out how this API is intended to be used. It
sounds like I could maybe just set SIGILL to be ignored and check the
errno after any math call. Or I could add the FPE handler to SIGILL as
well and treat them as synonyms.
