Quest Locked simply means being stuck in a zone that contains mobs for quests or has numerous NPCs to give quests and the resulting chain-quests that follow. An infamous trap is Stranglethorn Vale, especially Booty Bay. There are TONS of quests to do there and you could easily get "trapped" in that zone until level 45 or 50.
