TODOs

• .bisect in bin/blin can be undefined

• Often, retesting a module that fails when there's no pressure succeeds. (e.g. if an OOM kill happened, or a transient error like 'No candidates found matching identity' - consider a way to put these BACK in the queue for a redo with a fraction of the processing power at the end. Faster than a manual redo because we don't have to redo all the deps that already passed.
