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
