Overview
Библиотека кеширующего resolving-а - изначально писалась для имплементации neh http протокола, использующей корутины. Для предотвращения пробоя короткого стека корутин есть метод, предусматривающий вынос в отдельный тред собственно вызов функции резолвинга. Для предотвращения обращения к DNS серверам (использования вместо этого заранее заданных ip-адресов), предусмотрена ручка добавления alias-ов hosname -> ip-address (требование от метапоискового движка).
Из-за того, что библиотека разрабатывалась под задачу максимально быстрого резолвинга добавлены слои кеширования результатов resoving-а, - возможности сбросить кеш для того, чтобы получить более свежие адреса для указанного host-а нет.
