This'll begin a new loop about 60 seconds after the previous iteration finished. Not sure how exact you need to be in executing "at the beginning of every new minute" but this is the easiest thing I can think of.

Anyone know I'm actually doing myself a favor by sleeping at the top of the loop rather than at the bottom? I'm thinking it'll save memory that way - sleep before the variables are set, rather than after they're used. 

while(1){
    sleep 60;
    # do stuff;
}
