I'm pretty sure this is a different bug, because apparently the second thread
forks and runs the 'xrandr' command line program, rather than issuing the
equivalent X requests on the same connection.

It isn't obvious to me that there's even an X bug here. Does DRI2 let you
continue using the same context across screen reconfiguration events? If that's
supposed to work, then perhaps this is a server bug?
