I still see the message (with non zero pid).

Are you sure, because I don't and I also don't see how it can happen now.

I checked - I have work_fork.c up to date, work_fork.o, libntp.a and ntpd
have been rebuild/linked, "make install" in external/bsd/ntp does not
install anything new.

But actually I get the message reproducably on "/etc/rc.d/ntpd stop",
but also once at boot time.
