Rust is *much* happier after
https://cygwin.com/pipermail/cygwin-patches/2025q3/014297.html which will
be in cygwin 3.7.0-0.288.g8a5d39527f9a (and eventually 3.6.5).  Now I can
build it locally without limiting -j (which is -j 20 I think), and some of
the tests that were hanging are now working.

I've pushed update to 1.90.0 and --no-fail-fast to keep running tests.
I'm still working on getting them all to finish though, I keep running out
of disk space ;)
