It's an interesting idea that I hadn't thought of. There would have to
be an atomic file system operation to "commit" a compiled module -
getting that right could be a bit tricky (compilation isn't
deterministic, so the commit has to be atomic).
Then you would probably want to randomise the build order of each --make
run to maximise the chance that each GHC does something different.
Fun project for someone?
