Its also be really great when taking stack traces when things go wrong, or collecting stack dumps. For example we see that simulator keeps failing in CI due to leaked threads... but from which nodes? Does thread X relate to thread Y or is it from a different node? -- This is an automated message from the Apache Git Service.
