Hi,

I have been trying to use the State monad for concurrent applications and came up with a little library.[1] My "MState" uses an IORef to maintain the state between different threads. The library also offers a simple way to fork off new threads using its own "forkM" function. This function will asure that every thread in an "evalMState"/"execMState" call will be finished before the final result is returned.

The library is also on github.com.[2] Please let me know what you think of it and whether or not I should put it on hackage.

My thoughts on hackage:

* For Haskell, if it's not on Hackage it doesn't exist :)

* It's usually better to put it up on Hackage where someone will use it and then keep refining it as needed.

In other words, don't be shy!
