Regarding your remark, that the RTS multiplexes IO already I am usure how this works out in practice. The reason I write this wrapper is that I want a network server which can handle thousands of connections. And to not require a permanent thread for each I would like to use something like select in C or Selector in Java. I haven't found something like this in Haskell, hence the libevent wrapper. If you have any information how to write something like this without this wrapper I would be more than happy.
The current model for concurrency in Haskell is m lightweight user-threads working on n kernel threads, thus the threads are very cheap in Haskell and take advantage of a multicore. I think with the current model, the right choice for a web server in Haskell is a multi-threaded model. As a point of comparison, I remember that blog post which noted that its FastCGI was able to withstand more than 3000 hits by second (on a quite normal setting). -- Jedaï
