I don't quite follow.

It is the call to exit, _Exit/_exit, or quick_exit which decides
the sequence of process termination actions.

Particularly in C++ the quick_exit call must not run destructors
for thread local objects, since the standard mandates that.

Changing __cxa_thread_atexit_impl would be more complicated than
just changing quick_exit.
