In the future, hopefully once btrfs is a bit more mature, perhaps it
could be considered to make a new writable snapshot subvolume of the
system, and the use yum prefix to update the new subvolume. When you
reboot, the new subvolume can become the new root. 

a) Currently running system files aren't affected.
b) All upgrades are done online
c) the update would merely be a switching of the root device on next
reboot
d) you could even roll-back by remounting the old root subvolume as the
root fs.

This would be similar to "boot environments" in solaris. 

Of course, if btrfs wasn't in use, there could be some fallback?
