--- Comment #2 from Torvald Riegel <triegel at redhat dot com> ---
I don't see a significant difference between a deadlock and killing the process
-- at least from a security perspective. With the latter, a user might become
aware of the problem without starting a debugger; with the former, just another
pthread_once call would repair the deadlock, so make this a benign failure
(when ignoring performance).
