cleaned up, that value is added to the cleanup list. Cleanup finishes when there are no outstanding instances of
`boost::thread_specific_ptr` with values.
Note: on some platforms, cleanup of thread-specific data is not
performed for threads created with the platform's native API. On those
platforms such cleanup is only done for threads that are started with
`boost::thread` unless `boost::on_thread_exit()` is called manually
from that thread.
