No. I think the tentative plan is to just apply Oleg's "don't wait for
zombie threads with cred_guard_mutex held" patch, hopefully with that
de_thread() moved into install_exec_creds() (right after the dropping
of the locks).

But since it's arguably a user-level bug, and not a regression by any
means, it's not been exactly urgent. I suspect I'd like Oleg to
perhaps decide to take the patch up again.
