2328,Compiling DoCon with 6.8.3 has 3x slow-down compared with 6.8.2,simonpj,simonpj,"Serge reports that ""there remains the question:
why GHC 6.8.3 release candidate builds !DoCon-2.11 considerably slower than ghc-6.8.2
(3 times, as I recall)
and needs larger -M memory to build this !DoCon"".

A 3x slow-down wrt 6.8.2 is quite unexpected.
