Window became unresponsive during "Searching for obsolete software"

[Matt Zimmerman]

Binary package hint: update-manager

While upgrading from Jaunty to Karmic, I noticed that "Searching for obsolete software" was taking a long time with a lot of hard disk access. Soon thereafter, I saw the window become unresponsive (no progress bar updates, painted gray by compiz).

The log messages from this time period are:
