The only strange thing I noticed is that some groups have 0 limit. Is
this intentional?
grep memory.limit_in_bytes cgroups | grep -v uid | sed 's@.*/@@' | sort | uniq -c
      3 memory.limit_in_bytes:0
    254 memory.limit_in_bytes:104857600
    107 memory.limit_in_bytes:157286400
     68 memory.limit_in_bytes:209715200
     10 memory.limit_in_bytes:262144000
     28 memory.limit_in_bytes:314572800
      1 memory.limit_in_bytes:346030080
