Both POSIX and glibc use 'restrict' in pthread_create().
Let's use it here too.

.../glibc$ grep_glibc_prototype pthread_create
sysdeps/htl/pthread.h:212:
extern int pthread_create (pthread_t *__restrict __threadp,
__const pthread_attr_t *__restrict __attr,
void *(*__start_routine)(void *),
void *__restrict __arg) __THROWNL __nonnull ((1, 3));
sysdeps/nptl/pthread.h:200:
extern int pthread_create (pthread_t *__restrict __newthread,
const pthread_attr_t *__restrict __attr,
void *(*__start_routine) (void *),
void *__restrict __arg) __THROWNL __nonnull ((1, 3));
.../glibc$
