My 'puter turtled after deleting a movie: slowed to a crawl and hid dT behind the thinkin' ball for over 5 minutes.
Relevant console dumps:

I sampled the main dT program twice:

There were 2 'movietool' processes, also hanging:

http://www.ualberta.ca/~..._2009-12-23_sample4.txt
20 minutes after dT recovered, one of the movietool processes was still hanging:

It should be noted that iTunes was running the whole time. It could have been reindexing/verifying its library at the same time, but I doubt it (Does it even do that?), as it has been running for a few days.
