===== BISECT JOB RESULTS ===== Status: completed ===== SUSPECTED CL(s) ===== Subject : Reland #1: "base: Implement GetCurrentThreadPriority." Author : erikchen Commit description: The Chrome thread priority is saved in the thread dictionary during SetCurrentThreadPriority(). This seemed a better approach than using thread_policy_get(), since there are 4 Chrome priorities which won't cleanly map to thread flavors.
