Comment:

 This is beyond annoying. The windows tarballs are useless after this
 change. A full compile takes a day and a half in validate mode. even
 compiling a simple module now takes seconds.

 So I'm just going to kill SPLIT_OBJS as this change has effectively made
 it useless. Compiling a simple Cabal module alone takes 900 fork/exec
 calls.
