So I decided to try this in 3.13rc6 and I do still get the error. I see that
the verbiage of the error reported in syslog has been updated so I now see:

Jan  2 14:20:12 ossy kernel: [  128.655128] [drm] stuck on render ring
Jan  2 14:20:12 ossy kernel: [  128.655136] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Jan  2 14:20:12 ossy kernel: [  128.655137] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Jan  2 14:20:12 ossy kernel: [  128.655138] [drm] Please file a _new_ bug
report on bugs.freedesktop.org against DRI -> DRM/Intel
Jan  2 14:20:12 ossy kernel: [  128.655138] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Jan  2 14:20:12 ossy kernel: [  128.655139] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
Jan  2 14:20:12 ossy kernel: [  128.658048] [drm:i915_set_reset_status] *ERROR*
render ring hung inside bo (0x1260000 ctx 3) at 0x1261c20


Mesa was updated this morning and is: 
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Desktop 
OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.1.0-devel
(git-5a51c1b saucy-oibaf-ppa)

Intel driver:
[    32.143] (II) intel(0): SNA compiled: xserver-xorg-video-intel
2:2.99.907+git1401021930.4d8f78~gd~s (Oibaf <fmrummey at gmail.com>)

I reproduced the same way as my original bug report.  I also tried using the
"ilo" driver and Gallium acceleration, but they both hung with similar
messages.  I haven't tried it recently but only "NoAccel" made it impossible to
hit the desktop lockups.  

I will attach the new error file after this update.
