 Hi Daniel,

Tried your new yum on couple of C4 i386 boxes.  It is significantly
faster than the previous version.  Here is the output of a 'yum
check-update' :

The total time from the "before" run was 36.88 seconds.  It was < 5
seconds "after" the update.  By the way, why is it that the updated
version does not show info like the number of packages and the elapsed
time?
