 // The function __cxa_thread_atexit is provided by C++ runtimes like libcxxabi.
 // It is used by thread local object runtime to register destructor calls. To
 // actually register destructor call with the threading library, it calls
 // __cxa_thread_atexit_impl, which is to be provided by the threading library.
 // The semantics are very similar to the __cxa_atexit function except for the
 // fact that the registered callback is thread specific.

This comment is out of place now. Delete it or just leave a short note about how the above function relates to __cxa_thread_atexit. If you do that, make sure the comment goes before the function is is describing.
