    Description

      If a channel is closed just before a selector selects on it, it can cause indefinite hangs since there is no channel-closed signal (POLLHUP or similar) generated. The workaround is to only sleep for a maximum of 1 second when running on HP-UX; the caller of the corresponding await method already must retry in the event of a spurious wakeup.
