[Bug 830333] Re: randomly, update-apt-xapi will take 100% cpu for an extended period of time

[Tal Liron]

I can confirm that the fix mentioned above helps.

It seems that the Xapian updater is running for a much shorter time due
to using '--update' instead of a full recreation of the index. However,
since I don't really understand Xapian, I can't be sure that this
doesn't create other problems.

However, my netbook still stutters while watching a video during this
shorter period of time in which the Xapian updater is running. I think
that all the "nice" use in the world won't help this sore go away. I
hope Ubuntu can find an alternative solution.

Until then, can someone with authority look into confirming this fix and
patching it?
