What about
 - edit the ACLs & restart slapd to make the directory effectively read-only
 - use the hints in the admin guide to make an alternate slapd instance, 
   using a different datafile location
 - build the indices on the alternate slapd
 - stop both slapds
 - rename the datafile directories
 - put the normal slapd configs back in place
 - restart slapd

If having the main slapd read-only is a problem, I wonder if the alternate 
could be set up as a slave with slurpd pushing changes to it from the main 
directory?
