New failure mode showing up in Ubuntu test build:

[Long Running Test] 'Microsoft.ML.Tests.Scenarios.Api.CookbookSamples.CookbookSamplesDynamicApi.TextFeaturization', Elapsed: 00:58:11
[Long Running Test] 'Microsoft.ML.Tests.Transformers.WordEmbeddingsTests.TestWordEmbeddings', Elapsed: 00:58:08

Could there be a deadlock between these two? On my machine they finish in under a minute.
