The F#.NET Journal just published an article about concurrency:
"The MailboxProcessor in the F# standard library uses unbounded queues that can grow to be arbitrarily long. Consequently, the queue in a consumer can grow without limit if its producers overwhelm it with data. This article examines an elegant solution to this problem in the form of a bounded queue with asynchronous enqueue and dequeue operations that cause both producers and consumers to cooperatively suspend themselves until capacity or data are available to satisfy their request. Furthermore, this simpler architecture neatly decouples the sequential processes from the concurrent queues they use to communicate..."
