I believe IDLE itself implements the "restart" capability by killing
and re-launching its Python interpreter subprocess, so it's not like
it's using some hidden capability of Python to accomplish this.
Is doing Ctrl+D, up-arrow, Enter really that hard? It's even fewer
keystrokes than "restart()"...
