Right now I think it gets persisted out to disk with the rest of DRT's preferences, but I don't think that is a requirement. In fact, it's probably an accident that DRT's preferences get written to disk. So I don't think this presents a problem for concurrent testing, as long as we stop writing out preferences to disk.

Perhaps. Presumably that would require DRT changes. I also wonder if it would slow things down, since we'd be loading 3 files (prologue + test + epilogue) for every css2.1 test.
