I was imagining that it could create Module.o.compiling and then rename into place when it's done. Then each ghc would do a work stealing thing where it tries to find output to produce that doesn't have an accompanying .compiling, or sleeps for a bit if all work at this stage is already taken, which is likely to happen since sometimes the graph would go through a bottleneck. Then it's easy to clean up if work gets interrupted, just rm **/*.compiling _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
