Task Interference Issue

Hi, authers thanks so much for the excellent work! I would like to know whether the interference between tasks occurs if I repeatedly sample a minibatch from the task pool but DO NOT reset the AVD files and restart the emulator-[xxxx].

For example,

```
for i = 1 -> N:
    task_batch = task_pool.sample(bs)
    for worker_i = 1 -> bs:
        env.init_task(task_batch[worker_i])
```
