imho better way to solve this 'problem' would be to write error messages in such way that you don't need stdout as context to interpret them.

That's good to do, but you should flush things correctly anyway. Otherwise your error messages and output conflict.

Agreed, and using a standard logging library like log4* that gives your users a nice way to analyze their logs along with a timestamp of when they happened.
