Hello fellow Haskelleers, I've come upon a problem that sort of bites me. I'm writing a multithreaded webserver in which pages are dynamically loaded haskell applications. The main server loop listens for incoming requests and distributes these to request handlers, each running in a separate lightweight thread. Now, some of the most common operations used in dynamic web pages relate to directory listing/manipulation. I was happily thinking that System.Directory would provide the needed functionality. Indeed it does, but unfortunately setCurrentDirectory breaks the thread abstraction. What I mean is that if one page wants to change directory using setCurrentDirectory, this change affects all other (lightweight) threads as well, which is not how "ordinary" system threads works. Also it is clearly not what one would want in the kind of application I'm writing. Is this behavior of setCurrentDirectory intended? I can't see a situation in which you could take advantage of it, but that doesn't mean there can't be any. =) If it is not intended, is there any hope of it being "fixed"? Regards, /Niklas
