pthread_create() does allocate the TCB itself, and properly releases it
upon error while creating the thread, so the syscall wrapper does not
have to free any TCB memory by itself, which is a prerequisite to enter
the double release situation. There is no possibility to run the
deletion hook indirectly on behalf of pthread_create() either, so I
think it's safe.
