> Hence, using sigon/sigoff seems the wrong thing to do
Within Cython code, sig_on/sig_off is '''never''' the wrong thing to do.
It might be unneeded, might slow things down, but it is never wrong.
> Wouldn't sigon/sigoff slow the code down?
Yes, it would. Typically, the slowdown is in the 10ns~20ns range which is
very little unless it's done in a tight loop.
