I declare this not a bug. The docs do not promise that the Futures being returned are the same Futures that were passed in. They are not. They are (or at least may be) new Futures that represent the same event. Since Futures, when used as dict keys, use identity as equality, those new Futures will not be present as keys in the mapping of Futures passed in by the OP.

The docs do not promise that the Futures being returned are the *same* Futures that were passed in. They are not. They are (or at least may be) new Futures that represent the same event. Since Futures, when used as dict keys, use identity as equality, those new Futures will not be present as keys in the mapping of Futures passed in by the OP.
