Comment (by thomie):

 Phab:D985 has been merged into into Phab:D975, which has been merged into
 HEAD, but I'm not seeing the huge improvements that hsyl20 mentioned in
 comment:16.

 ||= GHC =||= RSS =||
 || 7.11.20151111 (HEAD) || 123M ||
 || 7.10.2 || 142M ||
 || 7.8.4 || 131M ||
 || 7.6.3 || 41M ||

 I compile `ghc A.hs -package ghc -package ghc-paths`, then run `./A`, look
 at the `RES` column in `top`, and convert from Kb to Mb.

 What am I missing?
