          Issue ID: 20926
           Summary: Autotester timing out does not say what operation
                    timed out
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: bugzilla at digitalmars.com

Making it very hard to figure out what actually hung, since the autotester runs
multiple threads.

For example,

  https://github.com/dlang/dmd/pull/11252

It should report something like:

  error: timed out running test 'dmd builtin'

instead of just:

  timed out after 3600 seconds, step failed
