--- Comment #12 from Vladimír Čunát <vcunat at gmail dot com> ---
Thanks for fixing this!
Slightly off-topic - I'm rather scared when I see such comments in released
glibc versions:
/* FIXME This violates the mutex destruction requirements. See
__pthread_mutex_unlock_full. */
I would really hate to have to debug a situation where memory gets reused and
kernel writes into it at some point later. (I understand the triggering
situation might be considered unlikely, but still...)
