This bug was fixed in the package ureadahead - 0.100.0-8
ureadahead (0.100.0-8) maverick; urgency=low
* Decrease the buffer size to just 8MB, after much testing we don't
need much more than this since it will be limited by the size of the
page cache anyway.
This is in lieu of a new version of ureadahead for Maverick, which
while work is ongoing, isn't ready for shipping at this time.
