Hi Evan,
I finally got around to applying/testing your patch on Windows XP SP3 32-bit. As expected, Wireshark continues to capture just fine.
The relevant code in gui_utils and tshark are very similar indeed, but there are some differences, so I'm not sure if they could be combined or not.
But as Guy pointed out in a subsequent response, perhaps pipes no longer need to be handled any differently on Windows anymore and we no longer need to wait for exit status? In truth, I haven't looked at this code too much and it's not really an area I'm too comfortable digging into right now.
