Good to know that you can get a readable program out of this, but that diff
in behaviour isn't reassuring.

Also, I don't see anything in there that would try to play with cgroups - I
was mostly curious about the use of the freezer, but don't see any in the
C code. Out of curiosity I ran a similar kernel that I tried before (without
the right configs), and it doesn't complain about missing cgroup options...
