- * the user with the pointer u has quit, but only to be REPLACED WITH A NEW USER WHO
- * BECAUSE OF ALLOCATION RULES, HAS THE SAME MEMORY ADDRESS! To prevent this, we
- * cross reference each pointer to the user's signon time, and if the signon times
- * do not match, we return false here to indicate this user is NOT valid as it
- * seems to differ from the pointer snapshot we got a few seconds earlier. Should
