[Haskell-cafe] Tutorial about low-level I/O in Haskell

Hi, while polishing a small library of mine, I ended up writing a tutorial about the use of hGetBufNonBlocking and the related Foreign.* functions you need to do fast, block-oriented I/O in Haskell. There is something to be said for literate programming. Using recent topics for inspiration, the text describes the implementation of a fast word-counting program. :-) Here is the URL: http://cryp.to/blockio/docs/tutorial.html Peter
