Start a server as usual:

xpra start --bind-tcp=0.0.0.0:10000 :10 --no-daemon

Then upgrade it from another terminal:

xpra upgrade --bind-tcp=0.0.0.0:10001 :10 --no-daemon

The upgrade happens, but the new server does not respond to ^C and its sockets are unreachable!

here comes the bisection:

• r3143 good
• 3900 good
• r4300 good
• r4700 good
• 5000 bad
• r4850 bad
• 4775 good
• r4812 bad
• r4783 good
• r4798 bad
• r4790 bad
• r4787 good
• r4789 good

So r4790 is bad, a seemingly innocuous change (see #420)... sigh.
