i suggest you to use IORef Bool instead - as it was said once by SimonM, it's safe to use in m/t environment, of course without all fancy features of MVar locking

Is it also safe for other types such as Int? And is this documented somewhere? If not it would be helpful to add this to the Haskell Wiki.
