Run by line is very slow when stepping through code in other cells/files/libraries #7246
Description
I am testing with this notebook:
https://github.com/fastai/fastbook/blob/master/08_collab.ipynb
- Find the cell with the code
learn.fit_one_cycle(5, 5e-3) - Start a RBL session
- While RBL is auto-stepping through code that we don't care about, the code runs very slowly. We expect this when debugging, but we also trigger expensive variables requests on every step. We should only do that when we will actually stop
