Check out the following: [CUDA streams do not overlap](https://discourse.julialang.org/t/cuda-streams-do-not-overlap/24879)

… and note that you can also use `ParallelStencil.ParallelKernel.@get_priority_stream(i)`.

However, you might rather want to create one or a few larger kernel instead of all these small kernels…
