Uh, we already do that, don't we?
http://developer.postgresql.org/cvsw...nd/port/win32/
socket.c?rev=1.10
has:

static int
pgwin32_poll_signals(void)
{
if (UNBLOCKED_SIGNAL_QUEUE())
{
pgwin32_dispatch_queued_signals();
errno = EINTR;
return 1;
}
return 0;
}

Are you testing this on 8.0.x? Or a pre-RC version of 8.1?

Yeah, we did this. I am thinking of just use simple mechanism of the win32
sockets, which could not pick up signals, but I would like to see if there
is any difference -- do you think there is any point to try this?
