ruote - reserve expression

reserve

Prevents two process branches from executing at the same time.

              pdef = Ruote.process_definition :name => 'test' do
                concurrence do
                  reserve :mutex => 'a' do
                    alpha
                  end
                  reserve 'a' do
                    alpha
                  end
                end
              end

(Nice and tiny example, turns a concurrence into a sequence…)
