  Modified files:
    libraries/base/GHC   Conc.lhs 
    libraries/stm/Control/Concurrent/STM TChan.hs TMVar.hs TVar.hs 
  Log:
  Add IO versions of the STM primitives that allocate new transactional variables:
  
    newTVarIO :: a -> IO (TVar a)
    newTChanIO :: IO (TChan a)
    newTMVarIO :: a -> IO (TMVar a)
  
  These can be used inside unsafePerformIO, unlike the STM versions.
