The actual value used (2) is unexpected, and explained inline. I'd like to have a config option for this so that we can test both ways (in theory, it could resort to copies on non-Windows systems too), but I don't see a `uimod.ui` handy. Alternately, I tried replacing the 3 `open()` calls in the `VolatileManager` with `util.posixfile()`, but that simply hung the test on Windows for some reason, I think on the same line that's indicated as failing above. (There was a `grep` command hanging around, as well as `hg -R test-repo serve --stdio`.)
