On Windows, I cannot safely unmount the volume: Windows tells me that
it cannot be safely unmounted (because watching a filer on it has a
handle open on the volume).  If I unmount the volume forcibly, I see
what you expected me to see: nothing.

I guess this means the "cannot safely unmount" message will have to do
on MS-Windows.
