Sure it would; just make the test server setup script run on cygwin properly.

Yes, absolutely. The more tests that set up their own mock servers, the better.
But while we're waiting for that, a "nuke DNS resolution"
approach makes tests behave repeatably, and would
even be useful after we implement the fix you propose,
as it would protect us from new tests that sloppily depend on
the public internet.
As someone pointed out, actually nuking DNS resolution
is kind of tricky; my patch did it for DLLs that use win32
networking, but not for DLLs that use native networking.
It probably can't be done the same way everywhere,
so I guess for Linux I'll punt and try shared library overriding.
