Comment(by jdemeyer):
Replying to [comment:14 was]:
> jdemeyer is remarking that as a general rule we should wrap code that
might send SIGFPE signals in sig_on/sig_off.
Yes, that's what I meant. I never said this code must be wrapped in
`sig_on()`/`sig_off()`, just that you should be aware of this. You
thought about the possibility and decided not to add
`sig_on()`/`sig_off()` which is a choice that can be defended.
By the way: it's almost impossible that simply adding
`sig_on()`/`sig_off()` would make the execution time jump from 281ns to
3.92µs, so probably you did something wrong there.
