Rails transactions issue with rollback.
...I have a transaction in which a duplicate key exception is being thrown
by MySQL. I assume this happens when I try to do a save. The problem
is that before the save, I do a destroy on another object as part of the

rescue Exception => exc
flash[:notice] = ....
end
end

Thanks,
Sam

single-treaded so I implemented end method in Rengine class to shutdown
R in each method. I thought this won't cause multi-thread problems in
this case because I terminate/destroy each R thr...
