Dear Haskellers

I've been writing a modest chapter for a book edited by Greg Wilson called "Beautiful code".  In the end I
decided to write about concurrency and transactional memory.  If you'd like to have a look at my first
draft, go here
       http://haskell.org/haskellwiki/Talk:SantaClausProblem

I would welcome constructive suggestions for improvement. The book is aimed at a general audience of
programmers, not Haskell geeks, so I have tried to explain everything necessary as I go along.  So if you are
not a Haskell expert, your input would be particularly valuable to me.

Happy Christmas

Simon
