why doesn't yum cache anything?

Ok, fair enough, those speeds are almost exactly proportional:

    rpm -qa | wc -l          =>   654
    yum -C list '*' | wc -l  =>  1798

    (5.93 / 16.41) / (654.0 / 1798.0)  =>  0.9934

Is there any kind of reasonable GUI for yum yet?  A lot of these
problems wouldn't matter if the "session" was longer, and it was only
doing all of this parsing once at startup, letting you do multiple
queries and installs without it needing to start over from scratch each
time.  I thought Ximian Red Carpet was fantastic and I really miss it.
