I have a batch task to do a complete site deploy (to get around Issue #2373). It
normally just takes a couple minutes.

Today I set it and walked away. I came back a couple hours later and it was hung
on the Javadoc task. I was going to just kill it, but there was no little red-x
button to do so. Even stopping and restarting the server via SMF did not kill
the job (it restarted it).

We need the ability to kill a running task.
