Steven Parkes updated LUCENE-846:
---------------------------------

    Attachment: LUCENE-846-test.txt

Okay, here's an old version of 847 that demonstrates the problem (at least it does for me.)

No looking at the rest of my half-baked code.

And there's a bunch of debugging turned on in the patch, too.

> If you hit an IOException, e.g., disk full, while making a cfs from its constituent parts, you may not be able to rollback to the before-merge process. This happens via addIndexes.
> I don't have a nice easy test for this; generating IOEs ain't so easy. But it does happen in the patch for the factored merge policy with the existing tests because the pseudo-randomly generated IOEs fall in a different place.
