cleanup kernelspec loading...
cleanup kernelspec loading - kernel_selector.set_kernel validates selection and triggers 'spec_changed.Kernel'. It does not start the session anymore. - notebook calls kernel_selector.set_kernel when: - kernelspec is in notebook metadata - session is loaded (e.g. no kernelspec metadata) - notebook starts session, loads metadata on spec_changed.kernel The only case where starting the session is not triggered by spec_changed is on notebook load with no kernel metadata
