I always found another meaning to this and most of the stuff on AMLOR. I thought it was a cry for help to Roger. 'The Machine' is Pink Floyd, that entity which has skipped eath twice and is still dormant; and here The Machine is calling for Roger to rejoin them and that they will always be there waiting for him; 'Sometimes I get tired of the waiting' and then a further message to tell him to hurry up; 'Nobody lives forever'. Pink Floyd work as a machine and at the moment they are a new kind of machine without Roger. Part 2 is just an extension; another piece of advice for Roger 'it's only a lifetime'.
