    print "Chroot FAIL"
    print os.getcwd()
except Exception as e:
    print "Chroot OK"

Nonblocking console input in Python

By Nemesis Fixx:

#check stdin for input...

        return select.select([sys.stdin], [], [], 0) == ([sys.stdin], [], [])

#check n terminate program on terminal condition,
