5. (20 pts) Problem 1.35. Run the program on your OWN laptop/desktop, and record the maximum number of child processes you see before your system crashes, as well as your machine's memory size. (For those who doesn't have this edition of the textbook, the problem is as follows: If you have a personal UNIX-like system 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 ruining the file system.)
