Hello !

I have a small trouble with my program under FreeBSD. I do fork() to
create new process, and new process must do something and exit, but
parent process must continue. The simplest program looks like this:

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

main()
{
 if (!fork())
  {
   printf("This is child, exiting ...\n");
   return;
  }
 while(1);
}

The created child process must write message and exit, but it doesn't exit
correctly. It hangs like "zombie" process until parent process exits.

Why it happens ? Is there any way to solve or walk around this problem ?

Pre-thanx.
