From: Johannes Schindelin <johannes.schindelin@xxxxxx>
It can take a while to gather all the information that `scalar diagnose`
wants to accumulate. Typically this happens when the user is in need of
quick solutions and therefore their patience is tested already. By
showing a little spinner that spins around, we hope to help the user
muster just a tiny bit more patience until `scalar diagnose` is done.
