A concurrent development system. ask Walter <email@example.com> for
details... I think the issue he's having is that to accept a commit, the
package must pass some set of project manager defined checks, and he's
trying to run the test suite among the configured checks.

You seem to be fairly optimistic about this. I have no real arguments
against; I hope you're correct.

I like the idea in principle; one objection is that, for example, proxy
testing may use different backends for storage. Currently, they get
tested against all configured storage types, while according to the
suggested partitioning they would be tested by default only against one
type (the "default"? selected by the user? what if all have to be

Most of the ones I know about simply append a "~".
