[ovs-dev] [PATCH] Use WaitForMultipleObjects for polling on windows. This works on all kinds of objects, e.g. sockets, files, especially ioctl calls to the kernel. One additional paramater is passed down in poll_fd_wait() to help WaitForMultipleObjects. latch is signaled with event, to be waited/polled by WaitForMultipleObjects() as well.

Since all we do is to be waken up to go back to the main loop I can sort the fds and or the events for the duplicates. Does that sound ok?

I used null events for the cases not used by windows. So it's currently not added to the array. I can always create event so no chance to pass a null event to poll loop.
