FWIW the power user who originally reported this issue tried this PR and it looks promising to not deadlock any longer. |

This is another deadlock introduced by #5160. In a nutshell, all tasks entering gather_deps must be handled / transitioned out of flight even though we're not trying to fetch all of the keys.
A second problem popping up is that the
TaskState.donewas not properly (re-)set causing dependencies to be fetched to be transitioned falsely.This also closes #5406
Follow up PR to establish an enum as the worker task state name: #5444
