This is a test for platform-specific functions that are known to be
unavailable when running on a Windows VM. We expect it to fail when
running on Windows. SocketTest>>expectedFailures makes this explicit.

If Squeak is running on a Windows VM, this test will fail, and the
failure is expected. It is an expected failure.

That seems reasonable to me.

If it is not clear what an "expected failure" is, then a good method
comment in TestCase>>expectedFailures might help. And if we cannot
agree on the method comment, then it's a sure bet that we should not
be fiddling with the implementation.
