Subject Re: Real world usage of the recipe LeaderLatch

Thanks a lot for your reply. Could you please name a few open source
projects that used LeaderLatch if you are aware of any? I'd like to take a
look at the code.

btw, What about issues reported in the links I mentioned? are they actual
bugs or just used in an unexpected way?
