omit CLONE_PARENT flag to clone in pthread_create
CLONE_PARENT is not necessary (CLONE_THREAD provides all the useful parts of it) and Linux treats CLONE_PARENT as an error in certain situations, without noticing that it would be a no-op due to CLONE_THREAD. this error case prevents, for example, use of a multi-threaded init process and certain usages with containers.
