The problem is the aliasing, which is happening each time your extension
is loading (so on the second load, it re-aliased your new method to
initialize_before_reformaz, so the your method ended up calling itself).

Try:

class PageContent
  unless method_defined? :__initialize_before_reformhaz
    alias initialize_before_reformhaz initialize

    def initialize(page)
      __initialize_before_reformhaz(page)
      globals.request = page.request
    end
  end
end
