任务？先去找老板吧。老板不在，hoho~

看一下warden的资料：
资源隔离：
network（stack per container）
mount（local mount table）
process（local process table）
IPC（shmget）
UTS（hostname）

shmget：用于Linux进程通信共享内存

3 wshd(parent)
  Before-clone-hook(mount overlayfs)
  clone(2) & make child wait
  After-clone-hook(create control group, network) 
  Resume child

4. wshd(child)
  Before-pivot-hook(no-op)
  pivot_root(2)
  After-pivot-hook(setup devpts, hostname)
  wait for requests from wsh

5. wsh
  request with argv, resource limits, and user
  proxy **STDIN**,STDOUT,STDERR
  read exit status and exit

再复习一下gorouter的源码。
  在csdn上发文
  
做leetcode？昨天那个求共线的节点max值。完成后，ThinkingInJava，13章String

容器部分还要重看，泛型部分
之后就是enum和注解

**scanner.nextInt is throwing an exception and the application is terminating.**

**If the JVM process exits with status 0, warden won't be able to tell that it failed.**
