In a similar fashion, I try to address all sorts of corner cases in my code, to the point of being called obsessive by some colleagues - but it definitely helped a few times with really stubborn and obscure bugs.

An extra log line here or there, or an e-mail sent to the admin in weird situations, goes a long way - provided that you don't generate many false positives, because no one pays attention to a program that cries "binary wolf" too often.

It's always surprised me how many people are happy with somewhat sloppy work, doing just enough to solve a particular issue. Most of the time it doesn't even come from management pressure, it's just the way people work.

Perhaps there is something wrong with me but I always want to dot all the i's and cross all the t's.
