What steps will reproduce the problem?
(1) Use commit queue
(2) pre-cq or cq usually fails 
(3) Error is typically "VMTests failed with Error 1", this is probably your fault
(4) It's never my fault
(5) Difficult to tell why "Error 1" occurred.

What is the expected result?
CQ failures should state which test failed. 
Flake tests should not block CQ.

What happens instead?
Time wasted digging though tons of logspam, to discover CQ failed due to known flake test (https://bugs.chromium.org/p/chromium/issues/detail?id=741110)
