the same behaviour for me with GHC 6.10.4 on Windows XP. If I set the
timeout value to 0, I get
*** Exception: Nothing
immediately. Any other value results in
*** Exception: connect: failed (Connection timed out (WSAETIMEDOUT))
after about 20 seconds. I don't know where the problem is, but I have
similar problems with the threadDelay function. There must be something
broken somewhere for some windows systems.
