This is triggered by pidof when it close the file after reading one of
the /proc/$pid/stat files.
Reverting 86acdca1b63e6890540fa19495cfc708beff3d8b (fix
autofs/afs/etc. magic mountpoint breakage) fixes that.
Any idea?
Was this ever fixed?

when I'm talking to journalists I just say "programmer" or something like that.
