Honestly i don't think closesocket will cause race conditions as long as you make sure in your codes no more I/O operations will be issued on the SOCKET after calling closesocket. All pending I/O operations will be aborted with failure. Do all sorts of cleanup jobs and forget about this SOCKET whatsoever. It'll be fine
