Scott Graham b47bf6c250 Fix tests when running on Win10
The Windows 10 loader starts a few extra threads before main(). In a few
of the test cases, the tests were relying on thread ordering (generally,
the test thread being at index #1). Instead, use other signals to find
the correct thread to verify.
