- Make sure that asynchronous resolves handled by Winsock are stopped before WSACleanup is called. This is implemented by ensuring that when Curl_resolver_kill is called (eg via multi_done) it will cancel the Winsock asynchronous resolve and wait for the cancellation to complete. Winsock runs the asynchronous completion routine immediately when a resolve is canceled. Prior to this change it was possible that during curl_global_cleanup "a DNS resolver thread created by GetAddrInfoExW did not terminate yet, however curl is already shutting down, deinitializing Winsock with WSACleanup() leading to an access violation." Background: If libcurl is built with the asynchronous threaded resolver option for Windows then it resolves in one of two ways. For Windows 8.1 and later, libcurl resolves by using the Winsock asynchronous resolver which does its own thread management. For older versions of Windows, libcurl resolves by creating a separate thread that calls getaddrinfo. This change only affects the former and it's already handled for the latter.
