ZvT where opponent never leaves

Fun sometimes, but not if you're being quiet and actually seeming as if to think you stand a chance when your main base has been destroyed, you're starting from scratch and the opponent has 4 expos. Imagine if he managed to fill the entire island with turrets. It's not harder than to tech to broodlords, but still. Annoying to say the least. Don't do this. Opponent player was Wyrm.david (EU).
