      Work Description: je-ik commented on issue #9151: [BEAM-7806] Revert 
"[BEAM-7785] synchronize watermark update with bundle processing"
URL: https://github.com/apache/beam/pull/9151#issuecomment-515158715
 
 
   Yes, the PR accidentally caused deadlock in the test. Synchronizing the 
watermark update unintentionally limited parallelism of bundle processing to 1. 
This didn't cause any issues with existing tests or validates runner, but 
affected the integration test, because it performs blocking IO (and depends on 
another bundle to be unblocked). I have added test case to direct runner that 
exhibits this behavior and will fix the original issue without limiting the 
parallelism.
