Per https://metacpan.org/pod/IO::Tty:
"Windows is now supported, but ONLY under the Cygwin environment, see
http://sources.redhat.com/cygwin/."
So I would suggest to make stuff a soft dependency (as Tom is
hinting?), and not worry about Windows specifically. It is not like
what we are dealing with here is specific to Windows anyway, so you
would have already sufficient coverage. I would not mind if any
refactoring is done later, once we know that the proposed test is
stable in the buildfarm as we would get a better image of what part of
the facility overlaps across multiple tests.
