It is just emulating a use case, in a real life use case of course it shouldn't
be a for loop. Suppose checking a device existance every some period, it
is possible for same error messages being printed again and again, may for
same device, may for different device, but it is from same source code
line. I suppose you can understand, but you did not.

Please stop being angry, I was trying to understand you. I hope you can
also think from different point of view.

Same to me, I will stop reply because I have tried my best but I'm
beginning have same feeling as you that is you just do not want to read
what I wrote, sigh.
