We've not observed any of our 1.2.6 servers wedging in this fashion.
However, we need to preserve our 1.2.5 servers because if we axe them
we can't do full updates yet (as per
https://bugzilla.redhat.com/show_bug.cgi?id=637852).
With any luck the upcoming update will fix our issue; this patch is
slated for 1.2.6.1?
