"docker images" slow on 0.7.3

[jots]

On ubuntu 13.10 I did:
wget http://get.docker.io/builds/Linux/x86_64/docker-latest -O docker

docker images is slow:

using docker 0.7.2
% time docker images
real 0m0.284s
user 0m0.014s
sys 0m0.005s

using docker 0.7.3
% time docker images
real 0m15.845s <----
user 0m0.011s
sys 0m0.005s

I believe this is also causing docker build commands to be excessively slow compared to 0.7.2 when re-building a container.

Previously it would skip over the cached images very fast, and now it takes about a second to recognise an image has been cached and the build is skippable. In some cases, rebuilding the images is faster than pulling them from cache. This issue severely slows down automated systems that often (re-)build containers.

I am experiencing exactly this behavior on an Ubuntu 14.04 box running docker 1.1.2.

sudo docker images 0.01s user 0.01s system 0% cpu 8.890 total
