Subject: Flush stdout as it can be redirected to log

Flush stdout as it can be redirected to log

It avoids mixed logs in Jenkins' console by flushing every message
printed by the forked programs as logger.info() does.
It must be complete by refactoring logger management in util functions
[1] and by preventing output buffering in forked programs.
