Hi! Some packages are frequently without substitutes, like Racket and MAME. Link between the two? They both take a long time to build. So I wonder if this is not because the build somehow timeouts. I see that there is a `timeout' property on packages like chromium, qtwebkit, etc. Would it make sense to add, say, a 6-hour timeout to the offending packages?
