I can live better with memory leaks (which may appear or not, I don't know,
they would probably vanish in the 128 GBs of cluster memory) than
inconsistent code, my experience during the last 5 years. And all process
are restarted once every night anyway.
One aspect may be: I changed the Silva core products only a few times while
our ETH products get sometimes updated once a week. The refreshing feature
is of course more important if a product gets updated often.
With the layout product we talk about, a refresh should be a easy to do
task. They tend to be updated often, mostly some minor CSS changes, which
should cause no impact to the service.
I think I'm not the ideal person to discuss internals like the dependencies
of the product, I would like to leave this to Benno.
