This seems to fix the problems with merges failing on dirty indexes.
I didn't have time to trace through all of the ramifications, but it
seems to me by doing a merge with the default index, we are getting
some kind of random state (or maybe the state of the last merge).

I'll have to road test this a bit more to be sure it's a fix, but maybe you can think about whether it's the righ thing (TM) to do in any case.
