That's not what people usually mean when they say "reset the interpreter" or
"unloading a module".

That's not really a good description of what's going on. "Wiping out all state"
usually implies that some non-state stuff, like the interpreter itself, remains.
Similarly, "unloading a module" is usually taken to mean that the process
continues to exist.

It's the same on Unix and Windows. You want something in the os.exec*() family
