threadDelay space leak under win32

[Philippa Cowderoy]

Using the binary distros of GHC 6.2.1 and 6.2.2 under Win2K, this leaks
12K of memory per second on my machine (as do larger programs using
threadDelay in the idle event of a wxHaskell app):

module Main where
import Control.Concurrent
main = (threadDelay 1000) >> main

I've no idea if it also happens on *nix platforms, or with a win32/cygwin
build.
