[Haskell-cafe] Parallel ghc --make

[Niklas Hambüchen]

I know this has been talked about before and also a bit in the recent
GSoC discussion.

I would like to know what prevents ghc --make from working in parallel,
who worked at that in the past, what their findings were and a general
estimation of the difficulty of the problem.

Afterwards, I would update
http://hackage.haskell.org/trac/ghc/ticket/910 with a short summary of
what the current situation is.

Thanks to those who know more!
