The old implementation knew too much about how wireguard-go worked. As a result, it missed genuine problems that occurred due to unrelated bugs. This fourth attempt to fix the health checks takes a black box approach. A receive func is healthy if one (or both) of these conditions holds: * It is currently running and blocked. * It has been executed recently. The second condition is required because receive functions are not continuously executing. wireguard-go calls them and then processes their results before calling them again. There is a theoretical false positive if wireguard-go go takes longer than one minute to process the results of a receive func execution. If that happens, we have other problems.
