Before someone responds complaining that 4500 images is too much and that is the problem, lets compare this to another popular public cloud:
$ time euca-describe-images --region=us-east-1 --all > ec2-us-east-1.log
real 0m29.942s user 0m16.641s sys 0m0.283s
$ grep ^IMAGE ec2-us-east-1.log | wc -l 93547
