Well, the book is not that good. It completely fails to explain deferreds
which are a central concept in Twisted. I only understood deferreds when
watching Bob Ippolitos screencast about Mochikit which implements the same
API as Twisted... Then I got back to the Twisted book.

I think it needs more work.
