They wouldn't see anything different, but Journal entries corresponding
to files we chose to delete wouldn't resume properly.

I disagree; I don't think we're filling up with small Write or Paint
documents, my intuition is that we're filling up with recent large
downloads and movies. In the case where the problem is a huge download
the user just made, your scheme results in deleting *everything*.
Since we disagree, maybe best to wait until we have some disk-full
images back from the field so that we can see what used up all the
space, before deciding the algorithm.
