Haskell Stack swallows RTS flags #74

I ran into an issue when I tried to get stack to generate .prof files with the +RTS flags. It seems like the stack/ghc on windows swallows the +RTS flags meant for the application! This bug means the windows code never even got the -N flag and wasn't even parallelized. One workaround is to run the benchmarks against the executable directly without calling stack (somewhere in .stack-work\install\xxxxxxx\bin) until this is resolved.

I just discovered a workaround in that thread I linked. We should change the command used to run skynet to:

stack build && stack exec skynet --RTS -- +RTS -N
