[Bug 553328] Re: Backend does not get terminated

[Issy]

Just fresh installed 10.04 LTS today...same as Nixloz. Went into System
Testing twice, Networking only,  to see what my wireless card was on my
X31, and exited out without completing the test.  Found after 5 minutes
the fan was running continuous, and "top" showed two "backend" processes
consuming 100% cpu. Manually killed both.

Bug description:
The impact of this bug is that when checkbox finished, the backend keeps running forever while consuming processing power the whole time. This fix simply makes sure that the backend finishes when the frontend finishes too.

When Checkbox is stopped, the backend_info plugin sends a kill signal to the backend process. However, since this process is running as root, then the Checkbox process is not allowed to send it a signal.
