bumping version 2.1.1.2 -> 2.1.2.0, as readTVarIO was added
bumping version 2.1.1.2 -> 2.1.2.0, as readTVarIO was added

It looks like when 2.1.1.2 was uploaded to Hackage, the export of
readTVarIO from Control.Concurrent.STM.TVar was removed manually,
although it is in the repository under the tag 2.1.1.2.  So the Hackage
2.1.1.2 and the darcs 2.1.1.2 differ by this one line:

*** stm-2.1.1.2/Control/Concurrent/STM/TVar.hs  2008-11-01 20:43:37.000000000 +0000
--- stm/Control/Concurrent/STM/TVar.hs  2010-04-22 09:49:01.000000000 +0100
***************
*** 19,24 ****
--- 19,25 ----
        readTVar,
        writeTVar,
        newTVarIO,
+         readTVarIO,
  #ifdef __GLASGOW_HASKELL__
        registerDelay
  #endif

To restore normality I'm bumping the version number and I'll upload a
new release to Hackage.
