Would be nice if this also checked to make sure session.save_handler wasn't set to something other than files first. I have my sessions in memcached, and this just caused a large outage on multiple wordpress sites.
I moved this post to it's own thread so we can address this concern separately.
I've opened internal case CPANEL-12637 to report this issue. I'll monitor the status of this case and update this thread with more information as it becomes available.
