From: Arne Schwabe <a...@rfc2549.org> 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.
