I can easily test this here, so you can throw any commands and tests at
me. ;)

This is the output:

Some other time I remembered getting directory names printed to the serial
console, which got killed because of this. This time it didn't happen.

Btw., When tried to remove the old directory without generating a new
poison one, I got some other traces. Seems like the above splash only
happens when I create and try to remove the directories in one run
(without reboot between).
