Thanks for your analysis! That sounds reasonable (I didn't recognize the
use of CLONE_NEWNS - just pasting from the examples ;-) - but I needed
it to mount a proc filesystem in the new PID namespace while using the
other one "outside"). So, I may not count on the /proc/{PID}/exe link
anymore in such cases as far as I see.
