Btw, one feature I don't know how to achieve with Jenkins (yet):

 - Try to build/test every single commit, while
 - priorizing latest commits,
 - work its way back during idle-time

(which is more or less what does)

For GHC, since it's properly submoduled now, it would suffice to test
each single commit in ghc.git. Having easily accessible metrics for each
single commit (on various configurations) would be very useful. 

For instance, knowing the last-known-working commit is especially
important if the latest commit fails to build (or exhibits some other
significant metric regression). In some cases this can save developers
time to git-bisect manually, as the answer is already in plain sight.

Does anyone have any idea how so set something like that up with
