Oh, good point. I didn't notice that.

I saw the same error with CUDA 11.5 and GCC 11 and fixed it by switching to GCC 9.

A few more comments on the `AsyncTransfer` struct. For this to work, all three of these need to have the same lifetime and making them all owned by the same...

Ok. Cool. I didn't know that. Just created one :)
