Also sometimes you have to go 'backwards' for whatever reason. You find the exact same issues.

Not as bad as it used to be but also just moving between platforms and staying on the same framework and things would act different. Because something in the OS layer was different. I ran into this quite a bit in python 2.x. Where windows and linux methods would be slightly different just because of underlying assumptions about how things like files were opened. That was when I learned your code is only as good as the std lib your platform provides. Take for example c++. The language itself is not terribly big. But that stdlib that goes with it (whew). Then you wonder would c++ be worth anything if that lib was not there?
