-------------------------+--------------------------------------------------
Two programs that generate modules with lots of let bindings that GHC
 struggles to compile. With the first,

 {{{
 ghc -c J.hs
 }}}

 uses >100M of memory which seems a little high. For the second,

 {{{
 ghc -c J2.hs
 }}}

 got past 700M before I killed it, with both 6.6 and HEAD.
