This is not news. It's been like that for several years, even before we had a 
decent CI system for Qt. UDP breaks all the time because, unlike TCP, it 
doesn't get tested well-enough and because there are subtle and incompatible 
differences between the OSes. 

I remember trying to maintain support for it when I still cared for Solaris, 
HP-UX and IRIX. It was a nightmare! I think at one point I concluded that the 
SO_REUSEADDR attribute on Solaris worked the opposite of what it was supposed 
to do, possibly due to a bug in the Solaris kernel.
