> {{GridSystemViewManager}} is not thread safe because it allows to registers walkers using public  {{registerWalker()}} that just adds walker to a {{HashMap}}.
> It seems the simplest solution here: make {{registerWalker()}} method private because it has usages only from {{GridSystemViewManager}} constructor.
