Well, this is not the final/perfect solution, but it is simpler:

ensure that signal(2,1) is first called, then this will do the job:

		local res = io.read()
		if not res then
			print 'ctrl-c caught'
			return ''
		end

where signal() is declared like this

require 'alien'
local lib = alien.load 'msvcrt.dll'  -- or alien.default for Unix
signal = lib.signal
signal:types{ret='int','int','int'}
