We installed and configured the buildtimeout plugin.

We now found it working, our builder exceeded the time set and got aborted.

The aborted state results in a gray icon and nothing more.

At least I expect a mail that the build got aborted. But I think it is a failure
of the build.
We use this buildtimeout to prevent a hanging build. We normally have a build of
4 minutes so I configured the buildtimeout on 10 minutes. Now due to a
implementation issue our build exceeded the 10 and we expected it to break.
