Comment:
Without a termlist table, we could allow "imperfect" deletion and
replacement of documents, where the term statistics aren't correctly
adjusted for the old document being removed. And xapian-compact could
recompute these statistics pretty cheaply (we'd have to scan all the
postlist chunks for a particular term before writing any of them in this
case, but that's not a big deal). This is essentially how Lucene works
AIUI.
