err about tag on code-3.2

[lvxingzhe]

切换到tag code-3.2,按照《自己动手写docker》上3.2小节root权限运行如下命令：

# git checkout code-3.2
# go build .
# ./mydocker  run -ti -m 100m stress  --vm-bytes 200m  --vm-keep  -m 1

产生如下报错

{"level":"error","msg":"fork/exec /proc/self/exe: no such file or directory","time":"2017-08-10T16:20:27+08:00"}
{"level":"warning","msg":"remove cgroup fail cgroup path error stat mydocker-cgroup: no such file or directory","time":"2017-08-10T16:20:27+08:00"}

能帮忙解决一下吗？
运行环境如下：
os: ubuntu14.04 ,linux 3.13.0.83
go:1.7.1

+1 我也遇到了

不好意思，这个是后来合代码合并的有点问题，需要把这个文件中的 container/container_process.go 这一行注释掉运行

新的fix的代码也已经推送上去了。
