[PATCHv3 01/11] run_processes_parallel: delimit intermixed task output

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This commit serves 2 purposes. First this may help the user who
tries to diagnose intermixed process calls. Second this may be used
in a later patch for testing. As the output of a command should not
change visibly except for going faster, grepping for the trace output
seems like a viable testing strategy.
