Outbound blocking by a firewall seems like a huge bet as to why things
might be looping.
Following that up, Tilghman. Just spoke to our network consultant who
will work with me on this as he gets back from lunch.
Jason says our firewall doesn't block outbound but I know it blocks some
inbound. Have not had this problem prior to CentOS 6.5...

We're running the curl loop (error state) and watching the net at the
firewall and there is little or no traffic out of the server while
trying to curl "http://mirrorlist.centos.org/?release=6&arch=i386&repo=os";
Network is good.

The weirdness only gets worse!
Our network consultant increased the size of the DNS return area (or
some such) on our firewall. Now, if I only use the nameserver 4.2.2.2,
I can run:
curl "http://mirrorlist.centos.org/?release=6&arch=i386&repo=os";
Subsequent yum calls hard loop on:
/usr/bin/python /usr/bin/yum some command (doesn't matter what yum command)
Common Man!!!
