updatedb, index, mergesegs
Can 'updatedb' and 'index' be performed concurrently on a segment?
Does 'mergesegs' require the segments to be index-ed or updatedb-ed before
merging?

No and no. Mergesegs creates its own (lightweight) index to perform
deduplication. It can also create the final index at the end of merging,
if you so wish.
