I did try to put just -N on the flags but it doesn't work.  I can see in 
top that ntpd is not running at higher priority as if the rc_flags were 
being ignored entirely.

The current setting is:

rc_flags="-N -u ntpd:ntpd -i ${ntpd_chrootdir} $rc_flags"

I added the -N, the rest was already there from the install.

Unless this isn't supposed to be called rc_flags.
