title: How to create a zombie process that cannot be reaped for a few minutes
body: <p>Could someone suggest me an easy way to create a zombie process that cannot be reaped for a few minutes.
  The purpose of this is to test parent process for being able to reap zombies processes after they become reapable again.</p>
  
  <p>One case for non-reapable zombies can be found <a href="https://stackoverflow.com/questions/19059615/process-stuck-in-exit-shows-as-zombie-but-cannot-be-reaped">here</a>. I guess there might be easier ways to do so.</p>
  
  <p>OS: Linux</p>
  
  <p>Preferable languages: C/C++</p>
