Comment 356 for bug 417757

I've pushed to the upstream repository a change which implements the second fallback mode. It is automatically used (after appropriate timeouts) or it can be requested with the new resolver option single-request-reopen.

Andreas will hopefully build a scratch glibc sometime soon (perhaps for F12, but that version could be used on F11, too). When this happens please test it and don't wait until after F12 is released, as it happened this time once again.
