 Review comment:
   `test_slide_factor (int, default - 3): how many slides there are in a single window (in
other words at most how many windows may be opened at time` -> `test_slide_factor (int,
default - 3): how many slides there are in a single window (in other words at most how many
windows may be opened at time for a given key)`
   
   Also it makes sense to explain the relationship between the `size` and the `factor`

> The test job should also test windowing. Sliding windows are probably the most demanding
form, so this would be a good pick for the test.
