Intermittent `distributed.utils - ERROR - 'cpu'`

See original GitHub issue

I just upgraded to the latest distributed/dask versions, and I am getting this intermittent keyError that’s difficult to characterize precisely and debug. I was wondering if anyone knows what’s the root cause for this issue?

I’m taking a look now. I think I see a way where this could happen. @andersy005 does this only happen just when a worker comes online?
