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.
