`/tmp/dask-worker-space-$UUID` then. Back to tmpfs vs. cwd: I'm very concerned about jupyter notebooks stored on NFS. Such notebooks will spill to NFS when they start a LocalCluster. I think that...

I believe #6241 is what you're looking for :) It's mosty done, it just misses unit tests and docs.

ts.previous == "flight". This is tightly related to #6705: The network stack raised, which caused `gather_dep` to return `GatherDepFailureEvent`, which is quite uncommon in real life and virtually untested.

Note that the scope of this issue is specifically about the state machine. The issue in the network stack is tracked separately, in #6875.

There are two failing tests. The amount of brain cells that died trying to understand them exhausted me, so I stopped work on this and I restarted from scratch on...

@fjetter I realised that `_transition_from_executing` is conceptually flawed. It assumes that we're getting there from one of the exit events of execute(), or in other words `assert ts.done`. Except that...
