### Вывод:
Из-за моментальной обработки сообщений в Consumer2, его очередь никогда не заполняется.
Consumer1 же тратит на обработку 2 секунды, из-за чего соответствующая очередь существенно заполняется при одном
запущенном экземпляре.
При нескольких запущенных экземплярах Consumer1 очередь заполняется существенно медленнее, и перестаёт заполняться совсем при определенном кол-ве запущенных экземпляров.
