The sign-off chain is unclear. Who is the author? What did the other person do? Thanks, Ben.
Author is me, Nikita found and analyzed the problem. You may change Signed-off-by to something more proper. Best regards, Ilya Maximets.

Thanks, I understand now. I applied this to master, changing Nikita's Signed-off-by: to a Reported-by:.

Windows even handling selector functions is such that it does not like when fd is -1 (I have not root-caused the exact reason). This commit causes most of the unit tests on Windows to fail. So the larger question is, even though fd of zero is valid, do we really pass it to any of our poll node functions?

I am trying to find the root cause also Guru, it seems that someone is passing an invalid handle.
