Sure enough, if you watch this application in Task Manager, you can see the memory usage going up smoothly over time. On my system, however, 10,000 iterations is not nearly enough; memory usage rises to about 6MB, and then it terminates normally. Also, it's definitely the WNetEnumResource call that does it. If you comment that out, there's no leak. It doesn't seem to be a Python garbage issue; I added a forced garbage collection in every loop, and it still happened. I haven't found any web articles about this.
