It matters not what the prefix says xntpd (NTPv3), but the version 
claimed in the banner is ntpd (NTPv4). The last time my paws fondled 
xntpd was seven years ago and that was version 3.5. Whether somebody 
updated to NTPv4 and changed the name of the program to xntpd is very 
retro, bot possible, and in that case claiming a recent NTPv4 version 
suggests cyberterrorist. In any case, the comment you cite in 
ntp_loopfilter.c is simply not there. Maybe it should be.

Over the years there have been many occasions when folks have added 
commentary to the distribution to "fix" or "explain" something. Makes me 
nervous, but I don't take those comments out.
