Problem 1: When a parent process attempts to run a very small program (a program that uses much less memory than the parent), why (under what conditions) might the OS cause the attempted fork() call to fail due to insufficient memory even though the machine has sufficient memory to run the new child program?
Problem 2: How does fork() complicate use of specialized hardware such as GPUs?
Problem 3: How would you teach the topic of "process creation" to new OS students?
