Maybe my brain has been baked too much by the sun, but I thought I'd seen cases
where a regression run on a patch with dependencies automatically validated
everything in the stack.  Not so?  That still places a burden on patch
submitters to make sure dependencies are specified (shouldn't be a problem
since the current tendency is to *over*specify dependencies) and on the person
starting the run to pick the top of the stack, but it does allow us to kill
multiple birds with one stone.

As for scaling, isn't the basic solution to add more worker machines?  That
would multiply the daily throughput by the number of workers, and decrease
latency for simultaneously submitted runs proportionally.
