TestResolvDNS#test_no_server always fails on usa's mswin environment
Every week usa (Usaku NAKAMURA) reports a test failure on his mswin environment like this:

It started roughly after timer thread was eliminated in Ruby 2.6.
Note that this is not reproducible on mswin RubyCI.
normalperson (Eric Wong) Do you have any insight for a possible cause of this?

FYI, I've never seen GREEN result of the test since last September.
The environment is Windows10 + Visual C++ 14.0(=Visual Studio 2015).
Do you have info on which revision it started failing with?
Timer-thread removal happened in August; and should only affect
thread_pthread; and mswin uses thread_win32, right?
Btw, feel free to email me directly for faster response.
I don't have time to follow Ruby closely, anymore.
