concurrent.futures.Future.add_done_callback: calling thread description error.

asyncio.run_coroutine_threadsafe will return a concurrent.futures.Future.
And according to its doc concurrent.futures.Future.add_done_callback() :

Added callables are called in the order that they were added and are always ** called in a thread belonging to the process that added them. **

But acually, the callback is called in where Future.set_result() is called according to its source.

Inizia dalla documentazione di concurrent.futures.Future.add_done_callback() e dal comportamento raggiunto tramite asyncio.run_coroutine_threadsafe; confronta la formulazione con il percorso del codice sorgente di Future.set_result(). Il lavoro è completato quando la documentazione descrive accuratamente il thread in cui vengono eseguiti i callback, considerando il PR collegato esistente prima di apportare modifiche.
