 cores with processes running an empty loop....

 I don't know, but regardless of what ghc does or doesn't do, your computer
 shouldn't just reboot itself. Try looking elsewhere for the cause of this
 problem, or workaround it by using `cabal build -jn`, where `n` is smaller
 than the number of cores you have.

 > and second, why does "cabal install" use 1 core, while "cabal build"
 uses many (by default).

 For me multiple cores are only used with either `cabal build -j` or `cabal
 install -j`, or when I set the jobs field in .cabal/cabal.config. If you
 still get different results, please open an issue with
 [https://github.com/haskell/cabal/issues cabal]. ghc by default doesn't
 use multiple cores.

 I'm closing this bug, as we won't make any progress on it, and there is a
 workaround.
