Why is Epiphany so chatty?

[Lee Revell <rlrevell joe-job com>]

Recently I switched to Epiphany from Firefox because it's faster.  I
need every ounce of speed on this slow machine.

But, it seems to be excessively chatty, by which I mean it insists on
loading pages from the network that I *KNOW* should be cached.  Browsing
from the cache seems impossible - as soon as you go into offline mode,
every page says it's not available.

The most recent example, I had opened a bunch of paged from nytimes.com
in separate tabs, then I disconnected from the net and was reading them.
X locked up and I had to reboot.  As soon as I launched Epiphany, I got
the "restore tabs" dialog.  I hit OK.

At this point I expect the pages to load from the cache.  But instead
Epiphany insisted on going online and re-downloading all the content.

I see this in non-error conditions too.  I can see it struggling to
download simple image banners like the New York Times logo every time I
go to the site.

IOW it does not seem to be using the cache at all!  What's the point of
having it?
