doc/Example.hs hangs on 'close pipe'

[nurpax]

doc/Example.hs hangs on Windows when running with MongoDB v2.0.4 (64-bit version). My Haskell is from the Haskell Platform, GHC version 7.0.3.

Basically this part:

main = do
    pipe <- runIOE $ connect (host "127.0.0.1")
    e <- access pipe master "baseball" run
    close pipe
    print e

hangs at the end of main. I run it like this:

runhaskell Example.hs

I'm not which part actually hangs. If I move "print e" above "close pipe" and insert logging prints between, it seems that "print e" completes, I get the full print out and execution hangs on "close pipe".

If I completely remove "close pipe", main exits without a hang.

The odd thing is that if I compile Example.hs with ghc and run the output Example.exe, there's no hang.

I'd be happy to help you guys debug this -- it'd be awesome to be able to use mongoDB on both Linux and Windows without issues.

I got the same hang also in structured-mongoDB examples. Ran them on Linux earlier today and didn't encounter any hangs.
