Thanks; that caused my original "plague-client kill 282" to produce a
traceback. I was then able to repeat the command, and it exited quickly
with:

$ plague-client kill 282
Success: job 282 killed.

This time it does seem to have worked.

There are still duplicates of gkrellm-freq-0_1_1-2_fc4 and
dejavu-fonts-1_12-1_fc3 in the queue, so the owners of those packages
may want to kill the dupes.

Paul.
