> Our SparkExecutionContext has an internal configuration {{ASYNCHRONOUS_VAR_DESTROY}} that indicates if rdds and broadcasts should be cleaned up in an asynchronous manner (true by default). However, it is incorrectly fed to the respective unpersist and destroy calls as a {{blocking}} parameter, which essentially makes all cleanup calls unwillingly synchronous.
