          Issue ID: 21179
           Summary: Test Suite: circleci times out with useless log
                    message
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

Here's the end of it:
--------
Makefile:208: recipe for target 'start_all_tests' failed make: *** [start_all_tests] Hangup

Too long with no output (exceeded 10m0s): context deadline exceeded
---------

But it's running a thousand tests in parallel, and gives no clue which one timed out.
