 Replying to [comment:26 jstolarek]:

 > BTW. Simon, you wrote the code for that patch when I was in Cambridge
 :-) Do you remember how we (well, mostly you) updated
 [http://ghc.haskell.org/trac/ghc/wiki/Commentary/Compiler/StackAreas this
 wiki page] and how we were confused with addressing offsets into an `Old`
 area?

 I am afraid that wiki page was not updated when I rewrote the stack layout
 algorithm, and it's woefully out of date.  In particular there are no
 `RegSlots` any more.
