Description
See commit 3ad5449927085b63f4304a13d534105004783bdd from Mathlib for a repro.
I've reported this a few times on zulip, but we better have a tracking issue.

Research direction
Start by reproducing the hang using Mathlib commit 3ad5449927085b63f4304a13d534105004783bdd, focusing on lake while it computes build jobs after an upstream file deletion. Trace the build-job computation to determine why it does not finish; done means the reported reproduction no longer hangs.
