I don't have an oar in this water, Terry, other than my bank no doubt has 
some python in its system, and its track record of bugs in the interface 
I'm being forced to use, which just Wednesday resulted in my calling one 
to their attention but I'd say that nudge needs to be set in a crontab, 
to repeat that nudge often enough to be effective.  I suspect what I 
experienced Wednesday was python3 growing pains, which the fact that 
they are working on it ahead of time, is encouraging.
