Okay, than I am good with it. I have a minor point, that we should stop downloading resources
if it is in the process of downloading resources. But I think that is a natural assumption.

This appears to be the behavior of WebKit's ApplicationCacheGroup::makeObsolete. It makes the
Group Obsolete, and removes Database entries without even checking for other documents
that may actively be using that ApplicationCache (HTML5 spec seems to make that point). Might
be a bug, or might actually work just fine.

What do you propose the interface for this be? How about:

  ApplicationCacheHost::deleteSomethingCacheGroup()

Where "Something" would be a more descriptive word like, "Associated", "Relevant", "Active",
or "Candidate". The spec doesn't give a technical name to this chosen relevant cache. I thought
an older version used the word candidate:
http://www.whatwg.org/specs/web-apps/current-work/multipage/offline.html#cache-host
