I've only had CUDA hang on me once in about 500 runs of the test suite due to parallelism, the AMD however stack fails about every other run. This should hopefully allow us to build in parallel, ever since I enabled the string conversion functions the test times have become more unreasonable. It may be worse on AMDGPU specifically because we run LTO on everything, but the `strtof` test alone takes about 44 seconds to build and run on my machine.
