In the spirit of incremental improvement ... I've taken Magnus' version and added the proposed change to re-enable Qingqing's patch by skipping WaitForSingleObjectEx altogether in the CHECK_FOR_INTERRUPTS code path. I also removed WaitForSingleObjectEx in pgwin32_poll_signals(), which AFAICS should be just like CHECK_FOR_INTERRUPTS. I think this is what we are proposing to actually apply to 8.1beta4. I can't test it though, so please check it over... regards, tom lane
