Indeed, this is particularly annoying for RMs.

An alternative to consider is using Travis for Windows CI[1], too.

To my knowledge, Appveyor “always” was way slower than Travis, and maybe
we're hitting the timeouts only now, since the size of the test suite
has increased.  Since our Appveyor CI runs with slow tests enabled, it
might be worth a try to disable these.  I've just submitted PR #3789[2]
to see whether that would make a big difference.
