You're welcome to try it yourself! Run IDLE without a subprocess by
passing the "-n" flag (e.g. python -m idlelib -n), then in the shell
do things that affect the entire process in various ways.

Some interesting examples: run a tight loop, run some long-running
code that runs compiled code rather than Python code, change global
state such as sys.stdout and sys.stderr, and on and on. Have fun
breaking IDLE!
