Taking a guess: You are writing to a highly contended entity group. Remember GAE gives you 1 transaction per second per EG, and regular nontransactional writes will automatically retry. So contention will produce long delays like this.
Think about your data model and make sure you aren't overloading a single EG. Either reorganize the data or come up with a sharding scheme. Unfortunately this is a difficult thing to do when you are already under load.
