> Redundant use of synchronize keyword

> In GroomServer.startNewTask(), we synchronize on the newly created
> TaskInProgress. This is unnecessary since it's a method local variable. I
> believe the intention was to synchronize on 'this' or on the collection
> runningTasks.
> Also, when the task is launched, I believe it doesn't need to be inside the
> synchronized block. The only field it accesses from the parent class is the
> configuration (conf).
> Patch attached.
> cheers
