 GHC 7.4.1 RC 2 User's Guide "RTS options for SMP parallelism" section
 describes not recommend way. Using getNumCapabilities function  from
 GHC.Conc instead of Control.Concurrent module, and using GHC.Conc's
 deprecated forkOnIO function instead of Control.Concurrent's forkOn
 function.

 GHC HEAD already fixed this problem by
 7d7809de3c6e264ae4af92c37da499502fc2fb20 with below base package's change
 ( 1b5f7ae2ffc6f3c851970efc26687763a4e0fc58 ).

 But ghc-7.4 branch doesn't fix this yet.

 Ian, could you please merge these changes.
