Comment (by dobenour):

 If rewritten in Haskell, it would be ''very'' easy to run `ghc-split` in-
 process – just run it in a separate Haskell thread, and send data to it
 over a pipe or channel.  That should solve the binary size worries.  In
 fact, the LLVM mangler could easily be made to work this way.
