| # 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. | |
