[Haskell-beginners] Working with System.Timeout in Windows

Hi Guys, I have been trying to do something with timeout of the System.Timeout but It hasn't work in Windows. When I first built, it didn't work, so I went to #haskell, and they told me that I should use -threaded, then after recompiling with -threaded it didn't work either. Does someone one what could probably be going on ? I'm using it with simpleHTTP of Network.HTTP, basically what I want to do is trying to get a source, but stop trying if I don't get an answer between a certain amount of time, something like: r <- timeout timeOutTime $ simpleHTTP req With curl for example I could use CURLOPT_TIMEOUT ( in Linux ), but I haven't found a way to say something like that using simpleHTTP. Cheers, Adolfo
