Same problem here with Kubuntu 10.10, apt-xapian-index 0.39ubuntu1. On my notebook with Celeron M 1,3 GHz processor & RAM 512 MB shared (464 available for the system) this process takes up to 91% CPU and eats the whole memory so that the system nearly freezes (takes up a a minute to open kickoff menu after the cursor finally made it to the button). The process interupts my work for about 10 to 15 minutes.
