Change subject: Ensure that all unit tests use unbuffered stdout and stderr ...................................................................... Ensure that all unit tests use unbuffered stdout and stderr stderr is normally always unbuffered but stdout can be buffered. Especially, when stdout is redirected it will become buffered while it is normally unbuffered when connected to a terminal. This mean that if the unit exits prematurely, the output in the buffered output will be lost. As the unit test x_msg mock implementation prints even fatal on stdout we ensure with this setup method that stdout is also unbuffered.
