Digging a bit deeper, it seems that GNU Hurd does not have a functional /proc/self link
(at least not Debian/Hurd 0.7).

  $ uname -a
  GNU hurd07 0.7 GNU-Mach 1.6+git20160114-486/Hurd-0.7 i686-AT386 GNU

  $ ls -l /proc/self
  lrwxrwxrwx 0 root root 1 Dec 31  1969 /proc/self -> 1

  $ od -ta /proc/self/cmdline
  0000000   i   n   i   t  sp   [   2   ] nul
  0000011

And so this test will never succeed as-is.

A relevant mention of /proc/self shortcomings is here:

Hope this helps,
