The *disk cache* is not part of WebKit, it is down in the Foundation layer. 
The in-memory cache in WebCore has been reworked recently, but we obviously
haven't changed the disk cache behaviour from WebKit.  My understanding of the
way the Foundation disk cache works is that it does expire resources
incrementally so the behaviour described would be a bug.  It'd be handy if you
could provide `sample' output from when Safari is hanging so we can see what is
going on.
