This method (i.e. `ThreadService::remove_thread()`) is called from
`Threads::remove()` *after* the thread was removed from the thread list:
void Threads::remove(JavaThread* p, bool is_daemon) {
...
// Maintain fast thread list
ThreadsSMRSupport::remove_thread(p);
...
ThreadService::remove_thread(p, is_daemon);
But if we reach here from `JavaThread::cleanup_failed_attach_current_thread()`
as the comment implies (`JavaThread::cleanup_failed_attach_current_thread()`
calls `Threads::remove()` in the case of an attach failure), calling
`ThreadService::incr_exited_allocated_bytes()` is probably irrelevant, because
a thread which failed to attach can't allocate anyway.
