If you have a personal UNIX-like system (Linux, MINIX, Free BSD, etc.) available that you can safely crash and reboot, write a shell script that attempts to create an unlimited number of child processes and observe what happens. Before running the experiment, type sync to the shell to flush the file system buffers to disk to avoid ruin­ ing the file system. Note: Do not try this on a shared system without first getting per­ mission from the system administrator. The consequences will be instantly obvious so you are likely to be caught and sanctions may follow.
