[Haskell-cafe] [ANN](and feedback request) unagi-chan: Fast and scalable concurrent queues for x86, with a Chan-like API

[Audun Skaugen]

Hi,
I get lots of import errors trying to build:
> tests/Main.hs:19:8: Could not find module `IndexedMVar'

Changing that import line to 'import Utilities':
> tests/Main.hs:18:8: Could not find module `Atomics'

Changing to 'import Data.Atomics':
> tests/Main.hs:15:8: Could not find module `UnagiUnboxed'

and so on.
