  # Emulation is incredibly slow and memory demanding. It seems that any
  # executable with GHC RTS takes at least 7-8 Gb of RAM, so we can run
  # `cabal` or `ghc` on their own, but cannot run them both at the same time,
  # striking out `cabal test`. Instead we rely on system packages and invoke
  # `ghc --make` manually, and even so `ghc -O` is prohibitively expensive.
