We have a Tkinter-based application that does DNS lookups (using socket.gethostbyname) in a background thread.
Under 1.5.2, this worked without a hitch. However, under 2.0, the same program tends to lock up on some computers. I'm not 100% sure (it's a bit hard to debug), but it looks like a global lock problem...
Any ideas? Is this supposed to work at all?
