Sorry, I don't get what the problem is, actually. What is the
relationship between ChildCount, Update signal and dynamic containers?
Could you show an example?

Well, "dynamic" doesn't mean that it changes very frequently. In fact,
some plugins, like Jamendo, change weekly, and others changes with more
frequency, like Youtube.

So far, I have never seen the problem you mention. In fact, it's similar
as browsing in any other online service that provides browsing through
pages. Flickr is such kind of service. And they do nothing to prevent
this problem. So I wouldn't worry about it, unless you really see this
is happening.
