Yes that does work.  However

while true do os.execute('echo hello world') end

cannot be stopped with ^C.  The only way to end it is to kill the whole terminal session.

What is hapening isthat the ^C is caught by the shell running inside os.exec(), so os.exec returns and the lua program loops again. You have to either have a lot of luck so the ^C arrives while the control is in lua code, or catch the return from os.exec and detect it was canceled.
For example, in Lua 5.1:

while true do
	if os.execute('echo hello world') ~= 0 then return end
