Set quiet period high enough that you can see builds waiting in the build queue
on the main Hudson page (or manually trigger a build with /build?delay=60sec or
something). The items shown in the build queue are links, with target URLs like:
/job/Test//parameters/queued/1234197302205/
which gets a 404 when clicked.

More importantly, the cancelQueue link shown here doesn't work. NOTE: prior to
issue #291 being committed, the link on the job name already didn't work, but
the cancel link DID work.

Another problem: during this quiet period, the build history list on the job
page doesn't show a Pending build (with a cancel X).
