Do you mean that Numba requires supporting multiple address spaces to be able to use tracemalloc? Or that supporting multiple address spaces would also to *also* track GPU memory allocations?

A friend told me that CUDA, OpenGL and OpenCL can (should?) be seen as 3 different address spaces. These libraries don't expose directly addresses in the GPU address space, but may use handles.
