Bug Description

Bad things are not specified (see https://dev.launchpad.net/ParallelTests : "If the base container is running it will be a disaster. Don't try."

Maybe a reasonable approach for us to limit the danger is to have a dedicated base container for the tests. If people also want to develop with lxc, they should use another container.

Consider that the base container's postgresql could/would write to the
launchpad test database files (e.g. make schema) while the higher
layers postgresql reads from it, and they wouldn't know about each
other doing that.

Yes, that works.
