I filed bug #1133926 a month ago, but as nbclient is a key package, it didn't cause autoremoval. As my out-of-sync bugs are closed immediately, the bug might have not caused your attention. nbclient fails to build on the buildds. =================================== FAILURES =================================== ______________________ test_many_async_parallel_notebooks ______________________ def test_many_async_parallel_notebooks(capfd):  """Ensure that when many IPython kernels are run in parallel, nothing awful happens.
