Dear GHC team,

I have compared for performance on DoCon of  
                                   ghc-7.4.1  registerised and unregisterised,
both made from source by  ghc-7.4.1
(Debian Linux, GenuineIntel, Intel(R) Core(TM)2 CPU),
DoCon and its test compiled under  -O
(-O2 is not better than -O). 

`registerised' is  5.4 times faster in building DoCon, 
               is  3   times faster in running the DoCon test,
               produces 1.7 times smaller .a library file for DoCon.
All right.
Please, keep on supporting the portable (via-C) branch.
