On the CI machine, the get_current_usage() is not immediately updated after the tmp_file is deleted for some reason so I'm using wait_for_condition() here to give it some time to update it.

Can you leave a comment on get_current_usage that it could be potentially flaky due to file size not being immediately updated + should be used with wait_for_condition?
