If I'm not mistaken, this is also the reason eunit tests do not capture
logger messages, making it hard to understand what was logged by a
specific failing test.
Is there something on the roadmap to try to address this issue ? It
affects both shell and eunit in non-trivial ways. The only workaround is
to ignore logger in applications and to write another log system which
uses the group leader, so it would make sense to fix logger.
