To avoid race issues, pthread::once() uses pthread_mutex. This caused the handle leak which was fixed by the commit 2c5433e5da82. However, this fix introduced another race issue, i.e., the mutex may be used after it is destroyed. This patch fixes the issue. Special thanks to Bruno Haible for discussing how to fix this.
