GHC CI

[Oleg Grenrus]

OTOH, if nightly pipeline is cancelled for a week in succession, and 
*then* it fails, we are screwed.

In my experience failing marge jobs is what consumes a lot of CI time.

In summary, until there is are analytics where the CI time is actually 
spent, it's at best guesses, at worst wrong guesses.
