OK, let me rephrase it: It is wrong to use sig_on/sig_off in comparison
code without "try-except". And, if I am not mistaken, "try-except" adds
another small overhead. I presume that comparison occurs very frequently
in many applications, and thus I'd go for speed.
That's to say: We should test both versions, William's and the "try-sigon-
sigoff-except" version, and compare timings.
