 * Error log messages are redirected to stdout to preserve the chronological order of the logs.
 * Furthermore writing to stderr from threads other than the main thread sometimes causes segfaults.
 * This seems to be related to the fact that stderr ist usually unbuffered whereas stdout is buffered.
 * However, I could not comprehend the problem.
