 This program, `process-run.py`, allows you to see how process states change as programs run and either use the CPU (e.g., perform an add instruction) or do I/O (e.g., send a request to a disk and wait for it to complete). See the README for details.

 4. We’ll now explore some of the other flags. One important flag is `-S`, which determines how the system reacts when a process issues an I/O. With the flag set to `SWITCH_ON_END`, the system will NOT switch to another process while one is doing I/O, instead waiting until the process is completely finished. What happens when you run the following two processes, one doing I/O and the other doing CPU work? (`-l 1:0,4:100 -c -S SWITCH_ON_END`)
 
 5. Now, run the same processes, but with the switching behavior set to switch to another process whenever one is WAITING for I/O (`-l 1:0,4:100 -c -S SWITCH ON IO`). What happens now? Use `-c` and `-p` to confirm that you are right.
