Comment 8 for bug 915158

In my example the dash process still exists until both sleeps have been finished. I have written a small testcase in C to check if its an applications fault if there are zombie processes:

#include <stdio.h>
#include <unistd.h>

int main()
{
 FILE *pipe;

 if((pipe = popen("echo", "r")) == 0)
 {
 }
 /*pclose(pipe);*/
 usleep(100000000);
 return 0;
}

This example will cause sh to get a zombie process if echo has finished until the main application finishes. But if I'm uncommenting /*pclose(pipe);*/ the zombie process will successfully clean up. So I'm assuming its the fault of the parent process if there are zombie processes because it isn't closing the related file descriptor.
