 Currently, changesets are generated when the "XAPIAN_MAX_CHANGESETS"
 environment variable is set to a non-empty value.  However, they are never
 removed.  Whenever a changeset is generated, the number of changesets
 around should be checked, and old changesets should be removed if too many
 old changesets exist.

 Alternatively (or as well), a different criteria might be useful for the
 changesets: it might be useful to be able to set an absolute limit on the
 total size of the changesets, or perhaps, a limit on the total size of the
 changesets as a proportion of the total database size.

 Finally, it is never useful to have a changeset for the first revision of
 a database, so creation of that changeset should be automatically
 disabled.
