Richi,
I looked at this code once but I really do not know this code at all and really
do not want to learn it. It will take a fair amount of time to try to figure
out what the underlying dataflow problem is and then figure out how to modify
it so that it is strictly monotonic (i.e. guaranteed to converge).
However, given that this is just improving debugging information, it should be
possible to just hack a count of the number of iterations and just stop after
20, i.e the way that flow used to do it.
If this is a blocker, this is what I would do to get the release out of the
door.
Kenny
