Uh, we already do that, don't we?
http://developer.postgresql.org/cvsweb.cgi/pgsql/src/backend/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?
