By the way, here's an example application which does just that using  
FastCGI: http://csmisc14.cs.chalmers.se/~bjorn/dynhs/examples/wiki/ 
wiki.hs

It uses a dynamically started FastCGI application, which means that  
the web server starts up new processes when needed and keeps a bunch  
of them around to serve future requests.
