Any idea was the atomically# mean in the following code?
atomically :: STM a -> IO a
atomically (STM m) = IO (\s -> (*atomically# *m) s )
Code is from GHC.Conc module
http://www.haskell.org/ghc/docs/6.6/html/libraries/base/GHC-Conc.html

Ha
I am having hard time making sense of GHC.Conc. Is there a writeup that
describes the significance of "#", or the meaning of "primOp" and
"primType"?
Thanks

This might be of some help:

It is a primitive
I like to look at the code where the runtime detects a TVar, inside an
atomic block, has been changed by another thread and hence it aborts the
atomic operation. Any suggestion as to where I would find the code?

That code is in /rts/STM.c
