> Since Flink 1.14.0, after enabling FlameGraphs and gathering statistics for a
> task, it doesn't aggregate the results from the parallel instances anymore
> but instead shows each individual one - something that easily gets too messy
> for higher parallelism.
> It seems the last shared method on the stack is
> {{Task.runWithSystemExitMonitoring}} and then it spawns off into individual
> lambda functions:
