-----------------------------------------------------------
Edit: leaving the below for historicity but 16 is EBUSY which indicates a
locked mutex.
The man page indicates EAGAIN is allowed but does not say when.
Original comment: Apparently pthread_mutex_init() and pthread_mutex_destroy()
can return EAGAIN, requiring a retry. I haven't dug into the kernel source to
determine what can cause this return code.
