[...] the (lack of) speed of running the Git test suite on Cygwin

the overheads of NTFS mean things are unlikely to get significantly
quicker any time soon, and between WSL and Git for Windows, I expect
interest in improving Cygwin's performance is going to continue to
wane.

Well, at least from the Git point of view, there is still _some_ hope. At
the Git Contributor Summit, we talked (very, very briefly) about moving
parts of Git's test infrastructure from shell code to C.

This would definitely help not only save electricity (and we all _do_ have
to get used to the idea that we cannot continue spending as much energy as
we do right now) when running the CI/PR builds, but also accelerate
running the test suite on Cygwin (or for that matter, I suspect HP NonStop
to be helped tremendously, too).

Ciao,
