Comment 5 for bug 1200519

Avery, in comment #2 you mentioned it started with 2.3.2-4ubuntu1 but I noticed this problematic behavior since at least the version shipped in Precise: 2.2.1-8ubuntu1.1.

The init script sleeps for 1 second between stop and start when asked to restart. As a temporary workaround, sleeping for 3 seconds give it enough time to cleanup after itself.
