In MT mode UI commands specific for worker-threads issued after the last beamOn of the job are not received by threads. This is because jobs exits without processing the last group of accumulated UI commands. A use case for this is user-defined commands that perform some action at the end of the job, for example, dumping information accumulated by threads or performing some analysis. To solve the problem we need to copy the logic of processing UI commands by threads also at exit of the job. Andrea
Bug re
The bugfix requires developments documented in https://jira-geant4.kek.jp/browse/DEV-216
Fixed starting from 10-02-ref-02. A new feature is present that allows to execute the commands stack in workers w/o a beamOn: this is achieved with a new specific UI command or automatically at the end of the job.
