--- Comment #1 from Serhei Makarov <serhei.public at gmail dot com> ---
Looks like this issue depends on PR22330. Once we have a proper transport
framework, we can implement a proper EXIT message instead of multiplexing onto
trace_printk() like this.
I experimented a bit with having exit() send a (much less likely to occur)
non-printing character to make the second testcase work properly, but that
introduces more problems than it solves.
