This is basically a rerun of this discussion a couple of years ago:

The problem certainly still happens against trunk -- I have a semi-aggressive test-harness which can cause it to reproduce pretty much on-demand. I proposed an approach here:

  http://mail.python.org/pipermail/python-dev/2008-April/078339.html

but when I started digging into test_support it all got a bit hairy because -- naturally -- test.support.unlink is used in a *lot* of places. In short, there's still a problem to be fixed. I believe that a rename-unlink dance would solve it, but only at the cost of affecting a lot of tests.
