Folks, I have committed some loop performance improvements that also fix the root cause of some diagnostic messages. The results are in: http://www.eecis.udel.edu/~ntp/ntp_spool/ntp4/testing/ntp-4.2.0b.tar.gz (and the regular FTP address for the same place). If you prefer, this is in the bk repo at pogo:~stenn/ntp-dev-danny . H
