This file has been causing problems for the build. ObjC was required for a few methods because autoreleasepools are necessary on new threads if those threads will be running objc code. This CL introduces a workaround by using ObjC runtime C APIs to create and drain autoreleasepools, but this comes with the cost of relying on an internal API that may break on future OS/clang releases.
