expungeDeletes was renamed to forceMergeDeletes, but it's a horribly,
horribly costly operation.
Normal merging will collapse the deletes anyway, and the default merge
policy favors segments with more deletions ... so you shouldn't have
to force merge
it seems that a doc is really deleted until next index merge or something.
I'm not sure.
