We now build a docker base container based on debian sid (where the very latest packages are available). That base container is updated once a month, or whenever travis-build.Dockerfile or debian/control change, but re-used for subsequent travis runs. While the initial build might take up to 15 minutes, subsequent builds typically run in a minute or two. All the different steps that we run on travis are now factored into separate scripts in the travis/ directory. Switching to docker should also help with issue #2174.
