Error in my_thread_global_end(): 2 threads didn't exit

=============================================================

In mysqld.cc:

  // Note: We can't call THD destructor without crashing
  // if plugins have not been initialized. However, in most of the
  // cases this means that pre SE initialization SST failed and
  // we are going to exit anyway.
  if (plugins_are_initialized)
  {
    net_end(&thd->net);
    MYSQL_CALLBACK(thread_scheduler, end_thread, (thd, 1));
  }
  else
  {
    // TODO: lightweight cleanup to get rid of:
    // 'Error in my_thread_global_end(): 2 threads didn't exit'
    // at server shutdown
  }

So, this bug is to track that and resolve it.
