I'm fairly new to the benchmark game so I would not be surprised if this is broken.

Previously I was adding them to a list but that caused OOMs.

Can you clarify what you mean? By 'return' do you just mean returning the deque from the method? Also I don't konw what a BlackHole is.

Apologies for not knowing what I'm doing here. Thanks.
