And I don't remember the config file.  If the target platform has a
config file with setting that change the performance so the described
behavior is possible, that's not a bug in NTP.

Again, if this is what happened and the config file directives make this
the stated behavior, that's not a bug in the code.  That's a
configuration file problem.

Sure, and we will need to see the bug duplicated on the latest version
of whatever branch has the problem, and with 4.2.8 nearly ready for
release and with almost no chance of another 4.2.6 release, it makes
sense for folks to focus on the latest -dev code.

If some volunteer feels like working on this for older code that's
great, and if somebody wants active support for older code that is
available too.
