The do_resolv action triggers a resolution and must wait for the result. Concretely, if no cache entry is available, it creates a resolution and wakes up the resolvers task. Then it yields. When the action is recalled, if the resolution is still running, it yields again. However, if the resolution is not running, it does not check it was running. Thus, it is possible to ignore the resolution because the action was recalled before the resolvers task had a chance to be executed. If there is result, the action must yield. This patch should fix the issue #1993. It must be backported as far as 2.0.
