Just applied the repo update rpm and the 4.4.3-6 updates - no problems.
I only saw one unexpected message in the 4.4.3-6 update - snippet below:
<snip> Running Transaction Updating : xen-licenses-4.4.3-6.el6.x86_64 1/10 Updating : xen-libs-4.4.3-6.el6.x86_64 2/10 Updating : xen-hypervisor-4.4.3-6.el6.x86_64 3/10 /var/tmp/rpm-tmp.kxFl1h: line 9: fg: no job control Updating grub config Updating : xen-runtime-4.4.3-6.el6.x86_64 4/10 Stopping xenconsoled Stopping QEMU <snip>
I went to look at the script in /var/tmp, but of course it is cleaned up... :}
didnt seem to bother anything.
