If src was overwritten by prctl(PR_SET_NAME) at this moment (i.e. after len was
calculated),

won't this result in inconsistent copying of src when length of src has changed
by prctl(PR_SET_NAME)?

This strncpy() assumes that length of src won't change within the function.
I thought prctl(PR_SET_NAME) might break such assumption.
