Yes, in fact that would be very welcome. PyCUDA has some complicated and brittle logic in place to manage CUDA's context stacks that I've been meaning to rip out. Here's an example: https://github.com/inducer/pycuda/blob/master/src/cpp/cuda.hpp#L525 Patches that get rid of all that code and simplify it would be very welcome.
