Well it's 3,000 source lines long, which is certainly big for GHC.
(-dshow-passes show big code and long times for each pass.) Maybe that's all
it is -- in which case it might be a good plan to split it up. But I also
wonder whether
* Some particular aspect of the code is triggering bad behaviour, perhaps
duplicating lots of code somehow.
* There is something badly non-linear, so that eg a file with a lot of top-level
defns takes a non-linear time to process. This seems entirely possible.
If you had a moment to look that would be great.
