Looking at the last 200 runs, the first visible failure seems to have been ~r205161

It is a very old bug, originated from bug144617. bug144622 fixed it more or less, but it seems cloop is still very slow.

Looking at build.webkit.org (https://build.webkit.org/builders/Apple%20Sierra%20LLINT%20CLoop%20%28BuildAndTest%29?numbuilds=200), I no longer see this failure. Let’s close this and open a new bug if the failure resurfaces.
