+Subject: [PATCH] Don't use pthread_detach() after pthread_join()
+
+After pthread_join() all allocated to thread resources are freed, so
+pthread_detach() after pthread_join() will results in undefined behavior
+with SIGSERV on some libc implementations (like MUSL). According to
+pthread_detach(3), "Either pthread_join(3) or pthread_detach() should be
+called for each thread that an application creates".
