What are you trying to achieve here by removing this from sys.path after adding it?

The import system will keep cuda_python_test_helpers in sys.modules, so any subsequent imports of it will just pull from that.

My understanding was its preventing polluting global state because the import path changes is alive for the duration of the lifetime of the interpreter process.
