I stand by my assertion that 2.6.34 does seem better in some regards. While
there certainly are still latency issues, it's now less often that heavy I/O
spills over into over processes' interactive performance. That being said,
earlier this evening Tracker and notmuch were both indexing and I saw several
events of tens of seconds of latency.
