Url to the build Failure:
https://build.chromium.org/p/chromium.linux/builders/Linux Builder/builds/69918

What is the bug or feature:
There was only 1 CL in the blamelist, however compile failed due to infra issue in compile.py where permission was denied.

This can cause false positives (as it has in this case) with compile try jobs, and incorrectly notify CL owners that their CL is causing breakages.

We should be able to extract when no "Failed: ..." messages but "Traceback (most recent call last): ..." can be suspect the failure could be infra-related
