+      # 1) Windows doesn't allow you to delete files that are open. This can naturally
+      #    occur when zef tries to delete itself, such as in one of the next steps where
+      #    we want to delete the existing zef install on the GH image (so we only have the
+      #    zef from whatever branch triggered this) or where we do a --force-install test
+      #    that tries to overwrite a precomp file in use.
+      # 2) Rakudo does not yet work around Windows path length limitations. This is a problem
+      #    due to the precompilation folder structure being fairly long as well as repos that
+      #    get cloned/extracted potentially having longer-ish names.
+      # Note RAKUDO_NO_PRECOMPILATION was added to rakudo as of 2023.08, so we can't test
+      # older versions of rakudo on windows.
