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

"""Utilities to enable code objects to be pickled.
Any process that import this module will be able to pickle code objects. This
includes the func_code attribute of any function. Once unpickled, new
functions can be built using new.function(code, globals()). Eventually
we need to automate all of this so that functions themselves can be pickled.
