Still needs some work, Ran it here and only got 38 packages, s/b 207 here. Timing on 1st run was
real 0m0.701s user 0m0.186s sys 0m0.019s
By the time we get 207 pkgs, I suspect a little overhead penalty.
I didn't change it to improve performance, for to get all the results correctly (previous one was missing some of them).
I really don't think there is any faster way to do it, since rpm accessing its db3 files is what costs so much on this. 10 or 100 dependencies should make little difference.
