Howdy,
Tom Crummey sent me a personal e-mail where he stated:

I too have an nVidia card on this machine. My driver version is
180.29
I went to the nVidia download website and found the latest driver
(180.51) for my graphics card. One of the highlighted fixes is the
following:
Fixed occasional X driver memory management performance problems
when a composite manager is running.
Doesn't specifically say `this bug will eat all of your RAM' but it
was the closest comment regarding memory. :)
I've downloaded the driver and will install it shortly.
FWIW, my monitor reports no significant memory increase yet. I'll
re-run it after I upgrade my driver.
