[winswitch] xpra unuseable on CentOS 5

Just one more thing: there is no guarantee at all that upgrading your
host OS will improve the behaviour of the application (especially the
focus issues you describe).
It sounds like upgrading is going to be a hassle for you, so you may be
better off trying it out in a virtual machine before spending too much
time down this path.
That said, moving away from CentOS 5 sooner rather than later is still
worth doing.
